possible to invoke Stop or Wait mode while in Standby mode for even greater levels of power reduction.
A 400kHz external clock can optionally be used in Standby mode to produce the required Standby 200kHz
system clock rate. Power-down mode, which selects the ROSC clock source but shuts it off, fully disables
the device and minimizes its power utilization but is only recoverable via reset.
When the PLL is not selected and the system bus is operating at 200kHz or less, the large regulator can be
put into its Standby mode (LRSTDBY) to reduce the power utilization of that regulator.
All peripherals, except the COP/watchdog timer, run at the system clock frequency or optional 3X system
clock for PWM, Timers, and I
operation is 32MHz.
6.6 Resets
The SIM supports five sources of reset, as shown in
external reset pin and the Power-On Reset (POR). The three synchronous sources are the software reset
(SW reset), which is generated within the SIM itself by writing the SIM_CTRL register in
the COP time-out reset (COP_TOR), and the COP loss-of-reference reset (COP_LOR). The reset
generation module has three reset detectors, which resolve into four primary resets. These are outlined in
