RMODE (bit 0) – Receive Mode. The receive section of the serial port is enabled when this bit is 1 and
disabled when this bit is 0. This bit is 0 at reset.
PDATA1 (07ah) - PIO DATA Registers.
PDATA0 (074h),
When a PIO pin is configured as an output the value in the corresponding PIO data register bit is driven
onto the pin. On the other hand, if the PIO pin is configured as an input, the value on the pin is input into
the corresponding bit of the PIO data register.
The following table lists the default states for the PIO pins.
