10.7
Port 8 is a 6-bit I/O port that also has other functions. Port 8 has the following registers. For the
port function control registers, refer to section 10.18, Port Function Control Registers.
• Port 8 data direction register (P8DDR)
• Port 8 data register (P8DR)
• Port 8 register (PORT8)
• Port 8 open drain control register (P8ODR)
• Port function control register 3 (PFCR3)
10.7.1
The individual bits of P8DDR specify input or output for the pins of port 8. P8DDR cannot be
read; if it is, an undefined value will be read.

Description
Reserved
When a pin function is specified as a general
purpose I/O, setting this bit to 1 makes the
corresponding pin an output port, while clearing this
bit to 0 makes the corresponding pin an input port.
Bits 4, 2, and 0 are reserved in the H8S/2424
Group.
