Description
Read / Write Bit
0 = Read
1 = Write
Message Identifier
000 0001 = Control Method and Fault Mask Configuration
Control Mode for Channel #x
0 = Current Control (RESET value)
1 = Direct PWM
Fault Mask for Channel #x
0 = faults don’t trigger FAULT pin (RESET value)
1 = fault triggers FAULT pin
Fault Mask for RESET_B pin
0 = RESET_B=Low doesn’t trigger FAULT pin (RESET value)
1= RESET_B=Low does trigger FAULT pin
Fault Mast for ENABLE pin
0 = ENABLE=Low doesn’t trigger FAULT pin (RESET value)
1 = ENABLE=Low does trigger FAULT pin
Diagnostic Timer
00 = divide by 128, nfault = 10 ... 11 (RESET value)
01 = divide by 192, nfault = 10 ... 11
10 = divide by 128, nfault = 2... 3
11 = divide by 256, nfault = 10 ... 11
