The realtime output trigger select register (RTPSR) sets whether the external trigger (TRIG pin
input) or the internal trigger (HSW) is used as an trigger input for the realtime output in a unit of
bit. For the internal trigger HSW, see section 28.4, HSW Timing Generation Circuit.
RTPSR is an 8-bit read/write enable register. When reset, RTPSR is initialized to H'00.
