Bits 2 to 0—Mode Select 2 to 0 (MDS2 to MDS0): These bits indicate the logic levels at pins
MD
MDS0 are read-only bits. The mode pin (MD
MDCR is read.

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.
