Section 9 Timers
Timer Control Register F (TCRF)
TCRF is an 8-bit write-only register that switches between 16-bit mode and 8-bit mode, selects the
input clock from among four internal clock sources or external event input, and sets the output
level of the TMOFH and TMOFL pins.
TCRF is initialized to H'00 upon reset.
Bit 7—Toggle Output Level H (TOLH)
Bit 7 sets the TMOFH pin output level. The output level is effective immediately after this bit is
written.
