CHAPTER 4 PORT FUNCTIONS
User’s Manual U16994EJ6V0UD
68
(1) Port mode registers (PM2 to PM4)
These registers are used to set the corresponding port to the input or output mode in 1-bit units.
Each port mode register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets these registers to FFH.
When a port pin is used as an alternate-function pin, set its port mode register and output latch as shown in
Table 4-3.
Caution
Because P21 and P32 are also used as external interrupt pins, the corresponding interrupt
request flag is set if each of these pins is set to the output mode and its output level is
changed. To use the port pin in the output mode, therefore, set the corresponding interrupt
mask flag to 1 in advance.
