SPI registers
The following diagram summarises the SPI address and control bits assignments.
Table 1. SPI Register and Control Bit Table
All other addresses are reserved. Write access to any of the reserved addresses will not have any effect, read access
will return 0
D08-D11 of writable registers to there POR- value (Reset-value). This values can be found in Table 1.
Bits regarding the driver outputs:
OUTx - Output driver latch
0
1
STATx - Output driver status
0
1
RHEx - Relay hold mode enable bit
0
state only depends on OUTx
1
PWM frequency fixed to 25kHz, duty cycle adapted to
