CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Remote Controller)
REMCR: REMCR output control (E0HD0)
Controls the REMCR (carrier) output.
When "1" is written:
REMCR output is enabled
When "0" is written:
REMCR output is disabled
Reading:
Valid
REMCR is the register to turn the carrier generation circuit ON/OFF and to enable/disable the REMCR
(carrier) output.
When "1" is written to REMCR, the carrier generation circuit turns ON and the REMCR output from the
REMCR (R00) terminal is enabled. The REMCR output timing is controlled according to the soft-timer
mode or the hard-timer mode.
When performing the REMCR output, the data register of the R00 output port should be fixed at "0".
When "0" is written to REMCR, it disables the REMCR output. It also turns the carrier generation circuit
OFF if REMDC has been set to "0".
At initial reset, this register is set to "0".
REMDC: REMDC output control (E0HD1)
Controls the REMDC (DC) output.
When "1" is written:
REMDC output is enabled
When "0" is written:
REMDC output is disabled
Reading:
Valid
REMDC is the register to turn the carrier generation circuit ON/OFF and to enable/disable the REMDC
(DC signal before pulse modulation) output.
When "1" is written to REMDC, the carrier generation circuit turns ON and the REMDC output from the
REMDC (R01) terminal is enabled. The REMDC output timing is controlled according to the soft-timer
mode or the hard-timer mode.
When performing the REMDC output, the data register of the R01 output port should be fixed at "0".
When "0" is written to REMDC, it disables the REMDC output. It also turns the carrier generation circuit
OFF if REMCR has been set to "0".
At initial reset, this register is set to "0".
REMSO: Soft-timer output control (E0HD2)
Controls the carrier output in the soft-timer mode.
When "1" is written:
Carrier output ON
When "0" is written:
Carrier output OFF
Reading:
Valid
REMSO is the register for the soft-timer mode to control the ON/OFF of the REMCR and REMDC outputs.
By writing "1" to REMSO when REMCR has been set to "1", Carrier is output from the REMCR (R00)
terminal. When "0" is written, the REMCR (R00) terminal goes to low level (VSS).
When REMDC has been set to "1", the content of REMSO is output from the REMDC (R01) terminal as a
DC signal. The REMDC output becomes high level (VDD) when REMSO is "1", and becomes low level (VSS)
when it is "0".
At initial reset, this register is set to "0".
Note: REMSO is for the exclusive use of the soft-timer mode. When controlling with the hard-timer mode,
REMSO should be fixed at "0".
RCDIV: Carrier cycle selection (E1HD3)
Selects the carrier cycle.
When "1" is written:
fOSC3/12
When "0" is written:
fOSC3/8
Reading:
Valid
RCDIV is the register to select the carrier cycle in the dividing ratio of the OSC3 oscillation frequency
(fOSC3).
When "1" is written to RCDIV, the carrier frequency is set to fOSC3/12. When "0" is written, it is set to
fOSC3/8. This setting must be done when the remote controller is OFF (REMCR = REMDC = "0") status.
At initial reset, this register is set to "0".
