4.3 Carrier Output
The carrier for remote-controlled transmission can be output from the REM pin by clearing (to 0) bit 2 of the control
register 0.
As shown in Figure 4-3, in the case where the timer stops when the carrier is at a high level, the carrier continues
to be output until its next fall and then stops due to the function of the carrier synchronous circuit. When the timer
starts operation, however, the high-level width of the first carrier may become shorter than the specified width.

Notes 1.
Error when the REM output ends: Lead by “the carrier’s low-level width” to lag by “the carrier’s high-
level width”
2.
Error of the carrier’s high-level width: 0 to “the carrier’s high-level width”
4.4 Software Control of Timer Output
The timer output can be controlled by software. As shown in Figure 4-4, the pulse with a minimum width of 1-
instruction cycle (64/f
X
) can be output.
