Description
Low-Speed On Flag
Specifies the operating mode to be entered after
executing the SLEEP instruction. This bit also controls
whether to shift to high-speed mode or subactive mode
when watch mode is cancelled.
When the SLEEP instruction is executed in high-speed
mode or medium-speed mode:
0: Shifts to sleep mode, software standby mode, or
1: Shifts to watch mode or subactive mode
When the SLEEP instruction is executed in subactive
mode:
0: Shifts directly to watch mode or high-speed mode
1: Shifts to subsleep mode or watch mode
When watch mode is cancelled:
0: Shifts to high-speed mode
1: Shifts to subactive mode
Noise Elimination Sampling Frequency Select
Selects the frequency by which the subclock (φSUB)
input from the EXCL pin is sampled using the clock (φ)
generated by the system clock pulse generator. Clear
this bit to 0 when φ is 5 MHz or more.
0: Sampling using φ/32 clock
1: Sampling using φ/4 clock
Subclock Input Enable
Enables/disables subclock input from the EXCL pin.
0: Disables subclock input from the EXCL pin
1: Enables subclock input from the EXCL pin
Reserved
An undefined value is read from this bit. This bit should
not be set to 1.
Reserved
These bits are always read as 0 and cannot be
modified.
