Functional Description

4.15 SLEEP State

The Sleep state is entered by asserting the Sleep Enable (R2/15) bit of the address map. During this mode,

the CLK pin is driven to a static logic low level, and the crystal oscillator is disabled. All digital outputs are

driven to a logic low level.

SPI operations are permitted during this state. The Idle state is entered by de-asserting the Sleep Enable bit

of the address map.
