6.8 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.
