Semaphore Unit (SEMA4)
3. Reads of the SEMA4_RSTGT location return information on the 2-bit state machine
(SEMA4_RSTGT[RSTGSM]) which implements this function, the bus master performing the
reset (SEMA4_RSTGT[RSTGMS]) and the gate number(s) last cleared
(SEMA4_RSTGT[RSTGTN]). Reads of the SEMA4_RSTGT register do not affect the secure reset
finite state machine in any manner.
Offset: 0x0100 (SEMA4_RSTGT)
