PRCM Functional Description
3.5.1.4
Reset Distribution
Each power domain can contain one power-on reset (RSTPWRON) and one or more reset (RST) signals.
These signals behave as follows:
•
On any global or local cold reset, RST and RSTPWRON are asserted.
•
On any global or local warm reset, only RST is asserted.
The CORE power domain receives two additional retention logic reset signals: retention reset (RST_RET)
and power-on retention reset (RSTPWRON_RET). These signals behave as follows:
•
On any global cold reset or wakeup from off state to active state, RST_RET and RSTPWRON_RET
are asserted.
•
On any global warm reset, only RST_RET is asserted.
•
On wakeup from retention state, these signals are not asserted.
The IVA2 power domain outputs the IVA2_RST_DONE signal, which handles the synchronous reset
scheme of the IVA2.2 subsystem.
shows the reset distribution among the 18 power domains.
