CHxF — Channel x Flag Bit
CHxIE — Channel x Interrupt Enable Bit
Freescale Semiconductor
When channel x is an input capture channel, this read/write bit is set when an active edge occurs on
the channel x pin. When channel x is an output compare channel, CHxF is set when the value in the
counter registers matches the value in the TIM1 channel x registers.
Clear CHxF by reading the T1SCx register with CHxF set and then writing a 0 to CHxF. If another
interrupt request occurs before the clearing sequence is complete, then writing 0 to CHxF has no
effect. Therefore, an interrupt request cannot be lost due to inadvertent clearing of CHxF.
Writing a 1 to CHxF has no effect.
This read/write bit enables TIM1 interrupt service requests on channel x.
1 = Input capture or output compare on channel x
0 = No input capture or output compare on channel x
1 = Channel x interrupt requests enabled
0 = Channel x interrupt requests disabled
