In Table 3, the B15–B10 are the control bits, so the each command depends on them (listed below).
1. B15-B10 = 0 0 0 0 0 1
These are the commands:
1) Phase AMP Sampling Hold Mode (B7 bit)
MM0: OFF (through) (INITIAL VALUE)
MM1: ON (use sample hold mode)
2) Phase AMP Short Mode [Short_Mode] (B6 bit)
MM0: OFF (no calibration) (INITIAL VALUE)
MM1: ON (use calibration mode)
2. B15-B10 = 0 0 0 0 1 0
These are the commands:
1) Phase AMP Gain (B7 bit and B6 bit)
MMB7:0 B6:0; Gain x1 (INITIAL VALUE)
MMB7:0 B6:1; Gain x2
MMB7:1 B6:0; Gain x3
MMB7:1 B6:1; Gain x4
3. B15-B10 = 0 0 0 0 1 1
Not used
4. B15-B10 = 0 0 1 0 0 0
This command is to read the diagnosis of the current regulator,
SPI communication, overvoltage detection, and input diagnosis.
5. B15-B10 = 0 1 0 0 0 0
This command is to read the diagnosis of SPI communication.
6. B15-B10 = 0 1 1 0 0 0
Not used
7. B15-B10 = Other command
This command sets the SPI-NG (DOUT, B7) bit.

1. B14-B9 = 0 0 1 0 0 0
This flag is cleared after the register is read by the CPU.
1) VCC Current Detection (B7)
MM0: NORMAL
MM1: Fail (Short to GND or open)
2) Overcurrent Detection (B6)
MM0: NORMAL
MM1: Fail (Overcurrent)
3) CAN Current Detection (B5)
MM0: NORMAL
