7.1.1 Examine Command

The Examine Command has four variations:

(1) EIxxxx - The Examine Instruction memory command.

This command permits the user to examine any memory

location within the 64K instruction memory space. The

EI command is followed by the 16-bit Hex address, above

as “xxxx,” of the memory location to examine. Valid

characters for the instruction address field (xxxx) are 0-

9 and A-F.

The user can examine consecutive memory locations by

repeatedly entering Space characters. The Monitor

continues to display the contents of contiguous memory

locations until any non-Space character is received. When

the Monitor receives a non-Space character, it terminates

EI command execution and waits for the next valid

Monitor command.

(2) EOxxxx - The Examine Operand memory command.

This command works exactly the same as the EI

command except that the user can now examine Operand

memory.

(3) EExxxx - The Examine External (I/O) command. This

command works exactly the same as the EI and EO

commands except that the user can now examine any

external I/O location.

(4) ER - The Examine Register command. The Examine

Register command allows the user to look at most of the

UT69R000’s internal registers.

After the UT69R000 has received the ER command, it

displays the contents of register R0. The user can examine

additional registers by repeatedly transmitting Space

characters to the UT69R000. The Monitor displays the

registers one after another in the following order: R0

through R15, Status/Output Discrete register (SW),

Pending Interrupt Register (PI), Interrupt Mask Register

(MK), Fault Register (FT), Timer A (TA) and Timer B

(TB). The UT69R000 continues to display its registers

until the UT69R000 receives a non-Space character

oruntil the UT69R000 has displayed the complete list of

registers. At this time the UT69R000 terminates the ER

command and waits for the next valid Monitor command.

7.1.2 Modify Command

The Modify Command has four variations:

(1) MIxxxx,vvvv - The Modify Instruction memory

command. This command permits the user to modify any

memory location within the 64K instruction memory

space. The MI command is followed by the 16-bit Hex

address denoted above as “xxxx,” of the memory location

to examine and the 16 bit Hex value denoted above as

“vvvv,” the user wishes to place in this memory location.

Valid characters for the instruction address field (xxxx)

and value field (vvvv) are 0-9 and A-F.

The user can modify consecutive memory locations by

entering multiple 16-bit values in the MI command. The

MI command would then take the form:

MIxxxx,vvvv,vvvv,...,vvvv where the user can enter as

many new values as desired. The commas are optional as

delimiters. The UT69R000 now modifies instruction

memory starting at the given address (xxxx) and

continues to modify memory until all new values are

in memory.

(2) MOxxxx,vvvv - The Modify Operand memory

command. This command works exactly the same as the

MI command except that the user can now modify

Operand memory. The form of the MO command to alter

multiple Operand memory locations is:

MOxxxx,vvvv,vvvv,...,vvvv.

(3) MExxxx,vvvv - The Modify External I/O command. This

command works exactly the same as the MI and MO

commands except that the user can now modify any

external I/O location. The form of the ME command to

alter multiple external I/O locations is:

MExxxx,vvvv,vvvv,...,vvvv.

(4) MRrr,vvvv - The Modify Register command. The Modify

Register command allows the user to modify most of the

UT69R000’s internal registers. The MR command is

followed by an 8-bit register ID code, denoted as rr, and

a 16-bit value, denoted as vvvv. Table 4 lists the register

IDs that the UT69R000 recognizes. Valid characters for

the register ID field (xxxx) and value fields (vvvv) are

0-9 and A-F.

The user can use only one MR command to modify one

UT69R000 register. Modifying additional registers

requires transmitting a separate MR command for

each change.
