Port Data Register 7 (PDR7)
Bit :
PDR77
Initial value :
R/W
R/W :
Port data register 7 (PDR7) stores the data for the pins P77 to P70 of port 7.
If PCR7 is 1 (output) when PMRB=0, the PDR7 values are directly read when port 7 is read.
Accordingly, the pin states are not affected. When PCR7 is 0 (input), the pin states are read if port
7 is read. When PMRB=1, port 7 pin functions as a realtime output pin. For details, refer to
section 10.8.4, Operation.
PDR7 is an 8-bit read/write enable register. When reset, PDR7 is initialized to H'00.
Realtime Output Trigger Select Register 2 (RTPSR2)
Bit :
7
RTPSR27
Initial value :
0
R/W
R/W :
Realtime output trigger select register (RTPSR2) selects whether to use an external trigger
(RPTRG pin input) or internal trigger (HSW) for the realtime output trigger input by specifying a
unit of bit. For details on internal trigger HSW, refer to section 26.4, HSW (Head-switch) Timing
Generator.
RTPSR2 is an 8-bit read/write enable register.
When reset, RTPSR2 is initialized to H'0F.
