R5 and R5IO register: R5 is an 8-bit bidirectional I/O
port (address 0CAH). Each pin can be set individually as
input and output through the R5IO register (address
0CBH).In addition, Port R5 is multiplexed with Pulse
Width Modulator (PWM).

The control register R5FUNC (address 0F6H) controls to
select PWM function.After reset, the R5IO register value
is "0", port may be used as general I/O ports. To select
PWM function, write "1" to the corresponding bit of
R5FUNC.
The control register R5NODR (address 0F9H) controls to
select N-MOS open drain port. To select N-MOS open
drain port, write "1" to the corresponding bit of R5FUNC.

R6 and R6IO register: R6 is an 8-bit bidirectional I/O
port (address 0CCH). Each port can be set individually as
input and output through the R6IO register (address
0CDH). R67~R60 ports are multiplexed with Analog Input
Port.

The control register R6FUNC (address 0F7H) controls to
select alternate function. After reset, this value is "0", port
may be used as general I/O ports. To select alternate func-
tion such as Analog Input, write "1" to the corresponding
bit of R6FUNC. Regardless of the direction register R6IO,
R6FUNC is selected to use as alternate functions, port pin
can be used as a corresponding alternate features
