Fig. 86 Real-time output structure in pulse mode 1
Table 14 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 corresponding 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.
