Timer Module (TIM16B8CV2)
16.3.2.4
Read: Anytime
Write: Anytime
16.3.2.5
The 16-bit main timer is an up counter.
A full access for the counter register should take place in one clock cycle. A separate read/write for high
byte and low byte will give a different result than accessing them as a word.
Read: Anytime

Output Compare 7 Data — A channel 7 event, which can be a counter overflow when TTOV[7] is set or a
successful output compare on channel 7, can cause bits in the output compare 7 data register to transfer to the
timer port data register depending on the output compare 7 mask register.
