(1) Port mode registers (PM0, PM1, PM5)
66
Symbol
Port functions are controlled by the following three types of registers.
PM0
PM1
PM5
These registers specify input or output mode for the port in 1-bit units.
These registers can be set by a 1-bit or 8-bit memory manipulation instruction.
RESET input sets these registers to FFH.
When port pins are used as alternate-function pins, set the port mode register and output latch as shown in Table
4-4.
