5.5.2
Clearing Subsleep Mode
Subsleep mode is cleared by an interrupt (timer A, IRQ
3
to IRQ
0
, INT
7
to INT
0
) or by input at the
RES
pin.
•
Clearing by interrupt
When an interrupt is requested, subsleep mode is cleared and interrupt exception handling
starts. Subsleep mode is not cleared if the I bit of CCR is set to 1 or the particular interrupt is
disabled in the interrupt enable register.
•
Clearing by
RES
input
Clearing by
RES
pin is the same as for standby mode; see section 5.3.2, Clearing Standby
Mode.
5.6 Subactive
Mode
5.6.1
Transition to Subactive Mode
Subactive mode is entered from watch mode if a timer A or IRQ
0
interrupt is requested while the
LSON bit in SYSCR1 is set to 1. From subsleep mode, subactive mode is entered if a timer A,
IRQ
3
to IRQ
0
, or INT
7
to INT
0
interrupt is requested. A transition to subactive mode does not take
place if the I bit of CCR is set to 1 or the particular interrupt is disabled in the interrupt enable
register.
5.6.2
Clearing Subactive Mode
Subactive mode is cleared by a SLEEP instruction or by input at the
RES
pin.
•
Clearing by SLEEP instruction
If a SLEEP instruction is executed while the SSBY bit in SYSCR1 is set to 1 and TMA3 bit in
TMA is set to 1, subactive mode is cleared and watch mode is entered. If a SLEEP instruction
is executed while SSBY = 0 and LSON = 1 in SYSCR1 and TMA3 = 1 in TMA, subsleep
mode is entered. Direct transfer to active mode is also possible; see section 5.8, Direct
Transfer, below.
•
Clearing by
RES
pin
Clearing by
RES
pin is the same as for standby mode; see section 5.3.2, Clearing Standby
Mode.
