The reset type status (RSTYPE) register is the only register for the reset controller.
6.7.7.1
Reset Type Status Register Description
The reset type status (RSTYPE) register latches the cause of the last reset. If multiple reset sources occur
simultaneously, this register latches the highest priority reset source. The reset type status register is
shown in
Figure 6-9
and described in
Table 6-22
.

NOTE
If a configuration pin must be routed out from the device, the internal pullup/pulldown
(IPU/IPD) resistor should not be relied upon; TI recommends the use of an external
pullup/pulldown resistor.
