Chapter 15 Timer Module (TIM16B6C) Block Description
15.3.2.14 Timer Input Capture/Output Compare Registers High and Low 2–7
Depending on the TIOS bit for the corresponding channel, these registers are used to latch the value of the
free-running counter when a defined transition is sensed by the corresponding input capture edge detector
or to trigger an output action for output compare.
Read: Anytime
Write: Anytime for output compare function.Writes to these registers have no meaning or effect during
input capture. All timer input capture/output compare registers are reset to 0x0000.

Read/Write access in byte mode for high byte should takes place before low
byte otherwise it will give a different result.
