Cautions 1. The settings of LVS50 and LVR50 are valid in other than PWM mode.
Remarks 1. In PWM mode, PWM output is made inactive by setting TCE50 to 0.
This register sets port 1 input/output in 1-bit units.
When using the P17/TO50/TI50/FLMD1 pin for timer output, set PM17 and the output latches of P17 to 0.
Set PM17 to 1 when using the P17/TO50/TI50/FLMD1 pin as a timer input pin. The output latch of P17 at this
time may be 0 or 1.
PM1 can be set by a 1-bit or 8-bit memory manipulation instruction.
RESET input sets this register to FFH.
Address: FF21H
Symbol
PM1
2. If LVS50 and LVR50 are read, 0 is read.
3. The values of the TMC506, LVS50, LVR50, TMC501, and TOE50 bits are reflected at the TO50 pin
2. Do not make settings <1> to <4> below simultaneously.
3. Stop operation before rewriting TMC506.
regardless of the value of TCE50.
