[13] PROT_DISABLE_05: Protection disable for CH5. As long as the bit is set, CH5 is kept actively OFF
0: Output enabled
1: Output OFF
Reset: 0
Reset Condition: POR, NRES
[12] PROT_DISABLE_04: Protection disable for CH4. As long as the bit is set, CH4 is kept actively OFF
0: Output enabled
1: Output OFF
Reset: 0
Reset Condition: POR, NRES
[11] PROT_DISABLE_03: Protection disable for CH3. As long as the bit is set, CH3 is kept actively OFF
0: Output enabled
1: Output OFF
Reset: 0
Reset Condition: POR, NRES
[10] PROT_DISABLE_02: Protection disable for CH2. As long as the bit is set, CH2 is kept actively OFF
0: Output enabled
1: Output OFF
Reset: 0
Reset Condition: POR, NRES
[9] PROT_DISABLE_01: Protection disable for CH1. As long as the bit is set, CH1 is kept actively OFF
0: Output enabled
1: Output OFF
Reset: 0
Reset Condition: POR, NRES
[8:1] OUTPUT_VOLTAGE:
Output voltage compared to LVT threshold (Low-Side)
0: VOUT < VLVT output ON
1: VOUT > VLVT output OFF
Reset: Initial OUTPUT_VOLTAGE field value depends on load
Reset Condition: POR, NRES
Output voltage compared to VOL threshold (High-Side)
0: VOUT < VOL output OFF
1: VOUT > VOL output ON
Reset: Initial OUTPUT_VOLTAGE field value depends on load
Reset Condition: POR, NRES
Note:
The OUTPUT_VOLTAGE[8:1] field value depends on external HW configuration. By default, all channels are
configured as LS NMOS. Hence, the default value of this field follows such interpretation.
[0] PARITY: Parity bit, based on even parity calculation
0: If the number of 1 is odd
1: If the number of 1 is even
