3. Timer load register C (TLC)
TLC is an 8-bit write-only register for setting the reload value of timer counter C (TCC).
When a reload value is set in TLC, the same value is loaded into timer counter C as well, and TCC
starts counting up from that value. When TCC overflows or underflows during operation in auto-
reload mode, the TLC value is loaded into TCC. Accordingly, overflow/underflow periods can be
set within the range of 1 to 256 input clocks.
The same address is allocated to TLC as to TCC.
Upon reset, TLC is initialized to H'00.
4. Clock stop register 1 (CKSTPR1)
CKSTPR1 is an 8-bit read/write register that performs module standby mode control for peripheral
modules. Only the bit relating to timer C is described here. For details of the other bits, see the
sections on the relevant modules.
Bit 1: Timer C module standby mode control (TCCKSTP)
Bit 1 controls setting and clearing of module standby mode for timer C.
