* 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.
When POWMAN_STATE_REQ is written, the POWMAN_STATE_WAITING flag is set while the Power Manager determines what is required. If an invalid transition is requested the Power Manager will still register the request in POWMAN_STATE_REQ but will also set the POWMAN_BAD_REQ flag. It will then implement the power-up requests and ignore the power down requests. To do nothing would risk entering an unrecoverable lock-up state. Invalid requests are: any combination of power up and power down requests any request that results in swcore boing powered and xip unpowered If the request is to power down the switched-core domain then POWMAN_STATE_WAITING stays active until the processors halt. During this time the POWMAN_STATE_REQ field can be re-written to change or cancel the request. When the power state transition begins the POWMAN_STATE_WAITING_flag is cleared, the POWMAN_STATE_CHANGING flag is set and POWMAN register writes are ignored until the transition completes.</description>
