The SM bit is cleared by external or power-on reset. The SM bit is automatically cleared when
entering STOP mode.
Note:
7.2
The slow/fast mode of the PLM D/A converters is selected by bits 1, 2, and 3 of the miscellaneous
register at address $000C (SFA bit for PLMA and SFB bit for PLMB). The slow/fast mode has no
effect on the D/A converters’ 8-bit resolution (see
7.3
On entering STOP mode, the PLM outputs remain at their particular level. When STOP mode is
exited by an interrupt, the PLM systems resume regular operation. If STOP mode is exited by
power-on or external reset the registers values are forced to $00.
7.4
The PLM system is not affected by WAIT mode and continues normal operation.
