4.3 Registers Controlling Port Function
(1) Port mode registers (PMxx)
148
Symbol
Port functions are controlled by the following eight types of registers.
PM0
PM2
PM3
PM6
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 signal generation sets these registers to FFH.
When port pins are used as alternate-function pins, set the port mode register by referencing 4.5 Settings of
Port Mode Register and Output Latch When Using Alternate Function.
Port mode registers (PMxx)
Port registers (Pxx)
Pull-up resistor option registers (PUxx)
Port input mode register 6 (PIM6)
Port output mode register 6 (POM6)
Reset pin mode register (RSTMASK)
A/D port configuration registers 0, 1 (ADPC0, ADPC1)
Port alternate switch control register (MUXSEL)
Note
Caution Be sure to set bits 2 to 7 of PM0, bits 4 to 7 of PM2, bits 1 to 7 of PM3, bits 2 to 7 of PM6 to
