RESET:
All of the reset sources are fed into the reset controller. The 16-bit reset status register
(RSR) reflects the most recent source, or sources, of reset. (Simultaneous reset re-
quests can cause more than one bit to be set at the same time.) This register contains
one bit for each reset source. A bit set to logic one indicates the type of reset that oc-
curred.
Once set, individual bits in the RSR remain set until software clears them. Can be
cleared by writing a one to the bit. A write of zero has no effect on the bit. The register
can be read at all times. The reset status register receives its default reset values dur-
ing power-on reset. The RSR is powered by the KAPWR pin.
