(Note) The oscillation circuits/external input that are not supported in this IC cannot be
selected as the clock source.
Note: The REMCLK register settings can be altered only when the REMDBCTL.MODEN bit = 0.

Bit 9
PRESET
This bit resets the internal counters (16-bit counter for data signal generation and 8-bit counter for car-
rier generation).
1 (W):
Reset
0 (W):
Ineffective
1 (R):
Resetting in progress
0 (R):
Resetting finished or normal operation
Before the counter can be reset using this bit, the REMDBCTL.MODEN bit must be set to 1.
This bit is cleared to 0 after the counter reset operation has finished or when 1 is written to the REM-
DBCTL.REMCRST bit.
Bit 8
PRUN
This bit starts/stops counting by the internal counters (16-bit counter for data signal generation and
8-bit counter for carrier generation).
1 (W):
