BLOCK SLEEP ENABLE REGISTERS

The Block Sleep Enables identified in the Block Sleep Enable Registers are described below in Section 7.8.4.1, "LPC

Blocks Sleep Enables Register," on page 136 and Section 7.8.4.2, "EC Blocks Sleep Enables Registers," on

page 137. The behavior of the Block Sleep Enables is described in "Block Sleep Enables," on page 117.

7.8.4.1

LPC Blocks Sleep Enables Register

Some LPC accessible blocks have no Block Sleep Enable bit in the LPC Blocks Sleep Enables Register. Table 7-44

describes these.
