The PMON Counter Mapping Registers (00H ~ 0FH) are updated as a group in the following three ways:
1. A transition from ‘0’ to ‘1’ on the UPDAT bit (b1, E1-0C2H) updates all the registers;
2. If the AUTOUPD bit (b0, E1-0C2H) is set to ‘1’, the registers will be updated every one second;
These bits together with the CRCE[9:8] bits count the CRC-4 Error numbers. The CRCE[0] bit is the LSB.
These bits together with the CRCE[7:0] bits count the CRC-4 Error numbers. The CRCE[9] bit is the MSB.
