CHxIE — Channel x Interrupt Enable Bit
CH01IE — CH0F and CH1F Interrupt Enable Bit
MS0B — Mode Select Bit B
MSxA — Mode Select Bit A
When TIM CPU interrupt requests are enabled (CHxIE = 1), clear
CHxF by reading TIM channel x status and control register with CHxF
set and then writing a logic 0 to CHxF. If another interrupt request
occurs before the clearing sequence is complete, then writing logic 0
to CHxF has no effect. Therefore, an interrupt request cannot be lost
due to inadvertent clearing of CHxF.
Reset clears the CHxF bit. Writing a logic 1 to CHxF has no effect.
This read/write bit enables TIM CPU interrupt service requests on
channel x.
Reset clears the CHxIE bit.
This read/write bit enables TIM CPU interrupt service requests when
CH0F and CH1F are set.
Reset clears the CH01IE bit.
This read/write bit selects buffered output compare/PWM operation.
MS0B exists only in the TIM1 channel 0 and TIM2 channel 0 status
and control registers.
Setting MS0B disables the channel 1 status and control register.
Reset clears the MS0B bit.
When ELSxB:ELSxA ≠ 0:0, this read/write bit selects either input
capture operation or unbuffered output compare/PWM operation.
