Note: When ECPWME in AEGSR is 1, event counter PWM is operating and therefore ECPWDRH
should not be modified.
When changing the data, event counter PWM must be halted by clearing ECPWME to 0 in
AEGSR before modifying ECPWDRH.
ECPWDRH is an 8-bit write-only register that controls event counter PWM waveform generator
data.

AEGSR is an 8-bit read/write register that selects rising, falling, or both edge sensing for the
AEVH, AEVL, and IRQAEC pins.
