CHxIE — Channel x 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 interrupts on channel x.
Reset clears the CHxIE bit.
This read/write bit selects buffered output compare/PWM operation.
MS0B exists only in the TIM channel 0 status and control register.
Setting MS0B disables the channel 1 status and control register and
reverts TCH1 to general-purpose I/O.
Reset clears the MSxB bit.
When ELSxB:A
operation or unbuffered output compare/PWM operation.

When ELSxB:A = 00, this read/write bit selects the initial output level
of the TCHx pin. See
1 = Input capture or output compare on channel x
0 = No input capture or output compare on channel x
1 = Channel x CPU interrupt requests
0 = Channel x CPU interrupt requests disabled
1 = Buffered output compare/PWM operation enabled
0 = Buffered output compare/PWM operation disabled
1 = Unbuffered output compare/PWM operation
0 = Input capture operation
1 = Initial output level low
0 = Initial output level high
