22.1.1
Four of the eight bits in the system control register (SYSCR) control the power-down state. These
are bit 7 (SSBY) and bits 6 to 4 (STS2 to STS0). See table 22.2.

Name
System control register
Bit 7—Software Standby (SSBY): This bit enables or disables the transition to software standby
mode.
On recovery from the software standby mode by an external interrupt, SSBY remains set to 1. To
clear this bit, software must write a 0.
