Power and Sleep Controller (PSC)

The Power and Sleep Controllers (PSC) are responsible for managing transitions of system power on/off,

clock on/off, resets (device level and module level). It is used primarily to provide granular power control

for on chip modules (peripherals and CPU). A PSC module consists of a Global PSC (GPSC) and a set of

Local PSCs (LPSCs). The GPSC contains memory mapped registers, PSC interrupts, a state machine for

each peripheral/module it controls. An LPSC is associated with every module that is controlled by the PSC

and provides clock and reset control.

The PSC includes the following features:

•

Provides a software interface to:

–

Control module clock enable/disable

–

Control module reset

–

Control CPU local reset

•

Supports IcePick emulation features: power, clock and reset

PSC0 controls 16 local PSCs.

PSC1 controls 32 local PSCs.
