RL78/F13, F14 CHAPTER 8 TIMER RD
R01UH0368EJ0210 Rev.2.10 603

[PWM3 Mode]
Access registers TRDGRAi to TRDGRDi in 16-bit units. Do not access them in 8-bit units.
The following registers are disabled in PWM3 mode:
TRDPMR, TRDDF0, TRDDF1, TRDIORA0, TRDIORC0, TRDPOCR0, TRDIORA1, TRDIORC1, and TRDPOCR1
Registers TRDGRC0, TRDGRC1, TRDGRD0, and TRDGRD1 are not used in PWM3 mode. To use them as buffer
registers, set bits TRDBFC0, TRDBFC1, TRDBFD0, and TRDBFD1 to 0 (general register) and write a value to the TRDGRC0,
TRDGRC1, TRDGRD0, or TRDGRD1 register. After this, bits TRDBFC0, TRDBFC1, TRDBFD0, and TRDBFD1 may be set
to 1 (buffer register).

Note The value after reset is undefined when FRQSEL4 = 1 in the user option byte (000C2H/020C2H) and TRD0EN =
0 in the PER1 register. If it is necessary to read the initial value, set f
CLK to fIH and TRD0EN = 1 before reading.

TRDGRAi — General register. The value of the TRDi register can be read at
input capture.
TRDIOAi
TRDGRBi TRDIOBi
TRDGRCi TRDBFCi = 0 General register. The value of the TRDi register can be read at
input capture.
TRDIOCi
TRDGRDi TRDBFDi = 0 TRDIODi
TRDGRCi TRDBFCi = 1 Buffer register. The value of the TRDi register can be read at
input capture (see 8. 3. 1 (2) Buffer Operation).
