Section 20 Power-Down State
Bit 7—Software Standby (SSBY): Enables transition to software standby mode. When software
standby mode is exited by an external interrupt, this bit remains set to 1 after the return to normal
operation. 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 clock to settle when software standby mode is exited
by an external interrupt. If the clock is generated by a crystal resonator, set these bits according to
the clock frequency so that the waiting time will be at least 7 ms. See table 20.3. If an external
clock is used,
