Fig. 99 Real-time output structure in pulse mode 1
Table 22 lists the port P5/RTP pin output when all of the port P5 di-
rection registers are set to the output mode.
Precautions for real-time output function
After reset, the port P5 direction register is set to the input
mode, and port P5i (i = 0 to 7) pins function as normal I/O port pins.
When using these pins as real-time output port pins, set the corre-
sponding bits of the port P5 direction register to the output mode.
Additionally, by reading the real-time output port’s value from the port
P5 register, output level of pins can be read out.
