(b) Pulse-width control register 2 (PCR2)
The PCR2 is used to select the timer operation modes.
Rewriting is possible only when bit 7 (EN) of the PCR1 is 0.
[Bit 7] FC: Function-select bit
Bit 7 is used to select the timer and pulse-width measurement functions.
[Bit 6] RM: Timer mode-select bit
At the timer function, this bit is used to select the modes below.
[Bit 5] TO: Timer-output bit
The value of Bit 5 is reversed each time the counter underflows. When the TOE bit (bit 6 of CSR1) is 1,
the contents of this bit are output from the WTO pin.
[Bits 3 and 2] C1 and C0: Counter clock-pulse select bits
Setting is made as shown below by a combination of these bits. These bits are not related to the value
of the FC bit.
[Bits 1 and 0] W1 and W0: Measured pulse-select bit
Setting is made as shown below by a combination of these bits. These bits are not relevant in the timer-
op eration mode (at FC = 0).
