8.4 16-BIT TIMER REGISTER 0 (TM0) OPERATION
8.4.1 Basic Operation
prescaler mode register 0 (PRM0).
(1) by software, the contents of TM0 are cleared to 0000H on the first count clock, and then the up-count operation is performed.
stopped.
is sent to the output control circuit. OVF0 bit is cleared by software only. The count operation is continued.
In the timer/counter 0 count operation, an up-count is performed using the count clock specified by the low-order 4 bits of
Count operation enabling/disabling is controlled by bit 3 (CE0) of timer control register 0 (TMC0). When the CE0 bit is set
When the CE0 bit is cleared (0), TM0 becomes 0000H immediately, and capture operations and match signal generation are
If the CE0 bit is set (1) again when it is already set (1), TM0 continues the count operation without being cleared.
If the count clock is input when TM0 is FFFFH, TM0 becomes 0000H. In this case, OVF0 bit is set (1) and an overflow signal
When RESET is input, TM0 is cleared to 0000H, and the count operation is stopped.
