General-purpose output port/BEEP tone shared-function output pins
The BEEP instruction switches between the general-purpose output port and BEEP tone
functions.
• General-purpose output port usage
The BEEP instruction with b3 = 0 sets up the general-purpose output port function.
Pins PN1 to PN3 are general-purpose output-only pins.
• BEEP output usage
The BEEP instruction with b3 = 1 sets up BEEP output.
The BEEP instruction bits b0, b1 and b2 sets the frequency.
When set up as the BEEP port, executing an output instruction will set the internal latch
data but has no influence on the output.
These pins go to the output high-impedance state in clock stop mode.
These pins go to the output high-impedance state during the power-on reset and hold that
state until an output instruction is executed.

Output-only ports
These pins go to the output high-impedance state in clock stop mode.
These pins go to the output high-impedance state during the power-on reset and hold that
state until an output instruction is executed.
General-purpose I/O ports
The IOS instruction is used to specify input or output.
The OUTR and INR instructions are used for output and input.
The bit set, reset and test instruction cannot be used.
In clock stop mode input is disabled and these pins go to the high impedance state.
During the power-on reset, these pins function as general-purpose input ports.
LSI test pins
These pins must be either left open or connected to ground.
