CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Remote Controller)
4.9.7 Programming notes
(1)
When using the remote control outputs, fix the R00 and R01 registers at "0" and do not change them.
(If the REMDC output is not used, the R01 register and terminal can be used as an output port.)
(2)
Except when outputting the remote control waveform, both REMCR and REMDC registers should be
fixed at "0" to prevent outputting unnecessary waveform and to reduce current consumption.
(3)
When performing remote output, it is necessary that the OSC3 oscillation circuit has already been ON.
Remote output should be started when the OSC3 oscillation is stabilized.
It takes at least 5 msec from the time the OSC3 oscillation circuit goes ON until the oscillation stabi-
lizes. Consequently, when starting a remote output, secure 5 msec or more waiting time for oscillation
stabilization after turning the OSC3 oscillation ON.
Further, the oscillation stabilization time varies depending ON the external oscillator characteristics
and conditions of use, so allow ample margin when setting the waiting time.
(4)
The setting of the RCDIV register (carrier cycle), RCDTY register (carrier duty ratio) and RT1/RT0
registers (
τ reference cycle) should be done when the REM circuit is OFF (REMCR = REMDC = "0")
before starting remote transmission. Changing the contents when the REM circuit is ON may cause a
malfunction.
(5)
When performing remote output in the soft-timer mode, be sure to control the carrier output using the
REMSO register. Do not control the carrier output using the REMCR register by setting the REMSO
register to "1". Similarly, in the case of REMDC output, do not control the output using the REMDC
register.
(6)
REMSO is for the exclusive use of the soft-timer mode. When controlling with the hard-timer mode,
REMSO should be fixed at "0".
(7)
When performing remote output in the hard-timer mode, do not write data to the ROUT3–ROUT0
register while the
τ waveform is high to prevent malfunction. Furthermore, next transmission data
writing should be done after the current carrier output is completed unless done intentionally. If this
register is written during carrier output, it stops output at that point of the falling edge of the
τ
waveform after the writing and starts new carrier output.
Furthermore, the ROUT3–ROUT0 register is for the exclusive use of the hard-timer mode. When
controlling with the soft-timer mode, be sure not to write data to this register to prevent malfunction.
(8)
When performing remote output in the hard-timer mode, do not write data to the RIC3–RIC0 register
while
τ waveform is high to prevent malfunction. If this register is re-written before generating the
interrupt corresponding the previous written data, the interrupt counter is renewed and the previous
set interrupt becomes invalid.
Furthermore, the RIC3–RIC0 register is for the exclusive use of the hard-timer mode. When controlling
with the soft-timer mode, be sure not to write data to this register to prevent malfunction.
(9)
The soft-timer mode and the hard-timer mode can not be used at the same time. To use them in
combination, set both REMCR and REMDC registers to "0" to stop the REM circuit before switching
the mode.
(10) Reading of interrupt factor flag is available at EI, but be careful in the following cases.
If the interrupt mask register value corresponding to the interrupt factor flag to be read is set to "1", an
interrupt request will be generated by the interrupt factor flag set timing, or an interrupt request will
not be generated.
