Description
Message Identifier
0 0111 = On/Off Control and Fault Mask Configuration
Control Mode for Channel #x
0 = Current Control
1 = On/off
Fault Mask for Channel #x
0 = faults don’t trigger FAULT pin
1 = fault triggers FAULT pin
Fault Mask for RESET_B pin
0 = A low state on the ENABLE pin does not activate the FAULT pin.
1 = A low state on the ENABLE pin does activate the FAULT pin.
Note: when a high to low transition is detected on the ENABLE pin,
the ENABLE fault will be latched until the ENABLE pin returns high
AND a diagnostic read message is received.
Fault Mask for ENABLE pin
0 = A low state on the RESET_B pin does not activate the FAULT pin.
1 = A low state on the RESET_B pin does activate the FAULT pin.
Diagnostic Timer
00 = TIME_1 pre-divider = 128
01 = TIME_2 pre-divider = 192
10 = TIME_2 pre-divider = 192
11 = TIME_3 pre-divider = 256
Auto-Zero Disable
