4.3 Device Resets
Four device resets are available – Peripheral Reset, Soft Reset, System Reset, and Power-On Reset. On completion of any of
the four reset cycles, all peripherals are reset. On completion of any reset cycle HCLK and PCLK are operational, the CPU
core receives clocks and power, and the device is in ACTIVE mode. Program execution begins at the reset vector address.
Contents of the Always-On Domain (AoD) are reset only on power-cycling V
DDA
and V
COREA
.
Each of the on-chip peripherals can also be reset to their POR default state using the two reset registers GCR_RST0 and
GCR_RST1.
Table 4-2: Reset and Low Power Mode Effects shows the effects of the four reset types and the four power modes.
