Register Name
TCRIT3 Mask
Register Name
Local Tcrit Limit
2.5.3 TCRIT3 Mask Register
The mask bits in this register allow control over which error events propagate to the TCRIT3 pin.
2.6 LIMIT REGISTERS
2.6.1 Local Limit Register
The Local Limit register range is 0°C to 127°C. The value programmed in this register is used to determine a local temperature
error event.
2.6.2 Remote Limit Registers
The range for these registers is 0°C to 255°C.

Description
Reserved – will report "0" when read.
Remote 4 Tcrit Mask:
1 – prevents the remote 4 temperature error event from propagating to the TCRIT3 pin
0 – allows the remote 4 temperature error event to propagate to the TCRIT3 pin
Remote 3 Tcrit Mask:
1 – prevents the remote 3 temperature error event from propagating to the TCRIT3 pin
0 – allows the remote 3 temperature error event to propagate to the TCRIT3 pin
Remote 2 Tcrit-2 Mask:
1 – prevents the remote 2 temperature error event from propagating to the TCRIT3 pin
0 – allows the remote 2 temperature error event to propagate to the TCRIT3 pin
Remote 1 Tcrit-2 Mask:
1 – prevents the remote 1 temperature error event from propagating to the TCRIT3 pin
0 – allows the remote 1 temperature error event to propagate to the TCRIT3 pin
Local Tcrit Mask:
1 – prevents the local temperature error event from propagating to the TCRIT3 pin
0 – allows the local temperature error event to propagate to the TCRIT3 pin
