5.6.1
Subactive mode is entered from watch mode if a timer A, timer F, timer G, IRQ
WKP
subactive mode is entered if a timer A, timer C, timer F, timer G, asynchronous event counter,
SCI3, IRQAEC, IRQ
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
Subactive mode is cleared by a SLEEP instruction or by a low input at the RES pin.
• Clearing by SLEEP instruction
• Clearing by RES pin
5.6.3
The operating frequency in subactive mode is set in bits SA1 and SA0 in SYSCR2. The choices
are φ
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 is the same as for standby mode; see Clearing by RES pin in section
5.3.2, Clearing Standby Mode.
