Section 9 16-Bit Timer Pulse Unit (TPU)
Bit 6—Reserved: This bit cannot be modified and is always read as 1.
Bit 5—Underflow Flag (TCFU): Status flag that indicates that TCNT underflow has occurred
when channels 1, 2, 4, and 5 are set to phase counting mode.
In channels 0 and 3, bit 5 is reserved. It is always read as 0 and cannot be modified.
