Description
Auxiliary system control register
Fields
AUXCTRL
Bits 7:2: Reserved
Bit 1: When clear, the LPOSC output is XORed into the TRNG ROSC output as an additional, uncorrelated entropy source. When set, this behaviour is disabled.
Bit 0: Force POWMAN clock to switch to LPOSC, by asserting its WDRESET input. This must be set before initiating a watchdog reset of the RSM from a stage that includes CLOCKS, if POWMAN is running from clk_ref at the point that the watchdog reset takes place. Otherwise, the short pulse generated on clk_ref by the reset of the CLOCKS block may affect POWMAN register state.
