Description
Reserved – will report "0" when read.
Remote 2 Tcrit-1 Mask:
1 – prevents the remote 2 temperature error event from propagating to the TCRIT1 pin
0 – allows the remote 2 temperature error event to propagate to the TCRIT1 pin
Remote 1 Tcrit-1 Mask:
1 – prevents the remote 1 temperature error event from propagating to the TCRIT1 pin
0 – allows the remote 1 temperature error event to propagate to the TCRIT1 pin
Local Tcrit Mask:
1 – prevents the local temperature error event from propagating to the TCRIT1 pin
0 – allows the local temperature error event to propagate to the TCRIT1 pin
