11.10 I/O Registers
11.10.1 TIM Status and Control Register (TSC)
MC68HC908LD64
Freescale Semiconductor
Rev. 3.0
Address:
The following I/O registers control and monitor operation of the TIM:
The TIM status and control register does the following:
TOF — TIM Overflow Flag Bit
Reset:
Read:
Write:
This read/write flag is set when the TIM counter reaches the modulo
value programmed in the TIM counter modulo registers. Clear TOF by
reading the TIM status and control register when TOF is set and then
writing a logic zero to TOF. If another TIM overflow occurs before the
clearing sequence is complete, then writing logic zero to TOF has no
TIM status and control register (TSC)
TIM counter registers (TCNTH:TCNTL)
TIM counter modulo registers (TMODH:TMODL)
TIM channel status and control registers (TSC0 and TSC1)
TIM channel registers (TCH0H:TCH0L and TCH1H:TCH1L)
Enables TIM overflow interrupts
Flags TIM overflows
Stops the TIM counter
Resets the TIM counter
Prescales the TIM counter clock
