Bit 0 ~ Bit 7 (P90 ~ P97) : 8-bit PORT9(0~7) I/O data register
You can use IOC register to define input or output each bit, and to
define the pull high condition.
Bit 0:
1. P90
:
can be defined as Input/Output
2. LED0
:
can be defined as Output
3. IR Input
:
can be defined as Input and IR is enabled
(when IOCF Bit7 is set to 1)
Bit 1 ~ Bit4:
1. P91~P94
:
can be defined as Input/Output
2. LED1~LED4 : can be defined as Output
3. INT1~INT4 : can be defined as Input
Bit 5 ~ Bit7:
1. P95~P97
:
can be defined as Input/Output
2. LED5~LED7 : can be defined as Output

Bit 0 ~ Bit 7 (CN28 ~ CN215) : Counter2_HB's buffer that you can read and write.
Counter2 is a 16-bit up-counter with 8-bit prescaler that
allows you to use R9 PAGE2 to preset and read the counter
(write
preset). After an interruption, it will reload the preset
value.
