Bit 4—Prescaler Select (PSS): Selects the WDT1 TCNT input clock. This bit also controls the

operation in a power-down mode transition. The operating mode to which a transition is made

after execution of a SLEEP instruction is determined in combination with other control bits. For

details, see the description of Clock Select 2 to 0 in section 14.2.2, Timer Control/Status Register

(TCSR).

Bit 4

PSS

Description

TCNT counts

φ-based prescaler (PSM) divided clock pulses

When a SLEEP instruction is executed in high-speed mode or medium-speed mode,

a transition is made to sleep mode or software standby mode

(Initial value)

TCNT counts

SUB-based prescaler (PSS) divided clock pulses

When a SLEEP instruction is executed in high-speed mode or medium-speed mode,

a transition is made to sleep mode, watch mode*, or subactive mode*

When a SLEEP instruction is executed in subactive mode, a transition is made to

subsleep mode, watch mode, or high-speed mode

Note:

When a transition is made to watch mode or subactive mode, high-speed mode must

be set.

MSTPCR comprises two 8-bit readable/writable registers that perform module stop mode control.

MSTPCR is initialized to H'3FFF by a reset and in hardware standby mode. It is not initialized in

software standby mode.
