Legend
0011XXYY = Serial (SPI) commands and status bytes (8-bit operation mode) MSB to LSB.
0 = Off command, SO OK status.
1 = On command, SO FAULT status.
X = Don’t care.
Y = Defined by state of X.
H = High-voltage level: Active state for inputs / gates, inactive state for outputs.
L = Low-voltage level: Inactive state for inputs / gates, active state for outputs.
