The realtime output trigger edge selection register (RTPEGR) specifies the sensed edge(s) of
external or internal trigger input for realtime output.
RTPEGR is an 8-bit readable/writable register. In a reset, RTPEGR is initialized to H'FC.
Bits 7 to 2—Reserved: These bits are always read as 1 and cannot be modified.
Bits 1 and 0—Realtime Output Trigger Edge Select (RTPEGR1, RTPEGR0): These bits
select the sensed edge(s) of external or internal trigger input for realtime output.
