TCNTSETUP()
TCNTSETUP() configures timer external clock input and 32-bit extension mode.
void TCNTSETUP(uint8_t timerNumber, bool on32bit = false)
Commands
| Command | Arguments | Return Value | Operation |
|---|---|---|---|
TCNTSETUP(timerNumber, on32bit) | uint8_t timerNumber — External clock timer number supported by the productbool on32bit = false — false: use only the hardware 16-bit counter. true: accumulate the upper 16-bit overflow count using overflow interrupts | void | Configures timer external clock input and 32-bit extension mode. |
Example
TCNTSETUP(1, true);
Precautions
- Timer external clock mode is supported only by MPINO-8A8R and MPINO-16A8R8T.
- Even on supported products, verify TCNT terminals and timer numbers using product documentation.
- Do not interpret
TCNTOUT()as a simple function for reading the current 16-bit counter. - In interrupt ISRs on other products, perform no work other than incrementing the count.
