MRm comparison output
Set 2 bits corresponding to nPIOm signal that is used to 1, 1 and set by PIO signal setting 1 command (21h).
Used as synchronous pulse output signal
As the action of a synchronous action, synchronous pulses can be output to nPIO0~nPIO3 signals.
For more details of the synchronous action, see chapter 2.6.
Used as MRm comparison output signal
The comparison result of MRm register can be output to nPIOm signal.
MR0~MR3 comparison output is output from nPIO4~nPIO7 signals.
For more details of the MRm register, see chapter 2.4.
[Note]
Note for using as output signal
nPIOm signal is pulled up to VDD with
50kΩ(Typ.) resistor inside MCX514. nPIOm signal is set to general input signal at reset.
Please note that the terminal voltage of nPIOm signal is at High level with
50kΩ pull-up until this signal is set to output by PIO
signal setting 1 command (21h).
Pull-up resistor inside MCX514 is
50kΩ standard, 20kΩ minimum and 120kΩ maximum.
