Power Immediate (Read Only). Reads return current value of Power Immediate bit.
Clear Power Immediate. Write 1 to clear the read only Power Immediate bit (bit 18).
Writing 0 has no effect. Reads return 0.
Set Power Immediate. Write 1 to set the read only Power Immediate bit (bit 18). Writ-

Description
Abnormal Work Delay Lock. After this bit is set, the value in this register can not be
changed until RESET_STAND# is applied.
Abnormal Work Delay Enable. Must be high to enable this function.
Reserved. By convention write 0, but may write anything. Reads return 0.
Abnormal Work Delay Delay. If the standby state is entered abnormally,
AWKD_
is allowed to be entered again, that is, a Standby Wakeup recognized.
