(3) Carrier generator output control register 40 (TCA40)
This register is used to set the timer output data in the carrier generator mode.
TCA40 is set using a 1-bit or 8-bit memory manipulation instruction.
RESET input sets this register to 00H.

When NRZ40 = 1, a carrier pulse is output to the TO40/P60 pin
1
When NRZ40 = 1, a high level is output to the TO40/P60 pin
NRZB40
This bit stores the data that NRZ40 will output next. Data is transferred to NRZ40 upon the generation of a
timer 30 match signal.
NRZ40
No return, zero data
0
A low level is output (the carrier clock is stopped)
1
A carrier pulse is output
Caution TCA40 cannot be set with a 1-bit memory manipulation instruction.
Be sure to set it with an 8-bit memory manipulation instruction.
(4) Port mode register 6 (PM6)
This register is used to set port 6 to input or output in 1-bit units.
When the TO40/P60 pin is used as a timer output, set the PM60 and P60 output latches to 0.
PM6 is set using a 1-bit or 8-bit memory manipulation instruction.
RESET input sets this register to FFH.
