Description
Software Standby
This bit specifies the transition mode after
executing the SLEEP instruction
0: Shifts to sleep mode after the SLEEP
1: Shifts to software standby mode after the
This bit does not change from 1 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
Reserved
This bit is always read as 0. The initial value
should not be changed.
