Section 3 MCU Operating Modes
Bit 7—Software Standby (SSBY): Enables transition to software standby mode. (For further
information about software standby mode see section 20, Power-Down State.)
When software standby mode is exited by an external interrupt, this bit remains set to 1. To clear
this bit, write 0.

Bits 6 to 4—Standby Timer Select (STS2 to STS0): These bits select the length of time the CPU
and on-chip supporting modules wait for the internal clock oscillator to settle when software
standby mode is exited by an external interrupt. When using a crystal oscillator, set these bits so
that the waiting time will be at least 7 ms at the system clock rate. For further information about
waiting time selection, see section 20.4.3, Selection of Waiting Time for Exit from Software
Standby Mode.

Bit 3—User Bit Enable (UE): Selects whether to use the UI bit in the condition code register as a
user bit or an interrupt mask bit.
