RSTCAUSE is updating incorrectly as 0xC, after a POR (NRST>1s) reset
When using NRST to trigger POR (NRST>1s) reset, RSTCAUSE is updating incorrectly as 0xC, which is expected as 0x2.
When need check reset cause, use one of the available SHUTDOWN memory bytes (SHUTDNSTOREx) to store a non-zero data after get RSTCAUSE status. When RSTCAUSE returns 0xC, then a POR occurs if the SHUTDNSTOREx data cleared, or a BOR occurs if the SHUTDNSTOREx data maintained.
