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): Start counting
0 (W): Stop counting
1 (R): Counting
0 (R): Idle
