Description
Software Standby
This bit specifies the transition mode after
executing the SLEEP instruction
0: Shifts to sleep mode after the SLEEP instruction
1: Shifts to software standby mode after the SLEEP
This bit does not change when clearing the
software standby mode by using external interrupts
and shifting to normal operation. This bit should be
written 0 when clearing.
Output Port Enable
Specifies whether the output of the address bus
and bus control signals (CS0 to CS7, AS, RD,
HWR, LWR, UCAS, LCAS) is retained or set to the
high-impedance state in software standby mode.
0: In software standby mode, address bus and bus
1: In software standby mode, address bus and bus
is executed
instruction is executed
control signals are high-impedance
control signals retain output state
