Release Factor
Release Method
RESETB
By RESETB Pin=Low level, Standby mode is released and system is initialized
KSCN(Key Input)
Standby mode is released by low input of selected pin by key scan Input(SMRR0,SMRR1).
In case of interrupt mask enable flag= “0”, program executes just after standby instruction,
if flag= “1” enters each interrupt service routine.
INT1,INT2
When external interrupt (INT1,INT2)
enable flag is “1”, standby mode is released at the
rising edge of each terminal. When standby mode is released at interrupt. Mask Enable
flag= “0”, program executes from the next instruction of standby instruction. When “1”,
enters each interrupt service routine.
Basic Interval
Timer(IFBIT)
When B.I.T. is executed only by bit10 of prescaler(PS10), SLEEP mode can be released.
Interrupt release SLEEP mode, when BIT interrupt enable flag is “1”. When standby mode
is released at interrupt. Mask enable flag= “0”, program executes from the next instruction
of SLEEP instruction. When “1”, enters each interrupt service routine.
