SPI registers map table

SPI frame has 7 bits address field and 20 bit data field, then the available address space consists of maximum

128 different registers. Taking into account the logical and physical partition of the functions configurable/

monitored by SPI interface, address space has been splitted in pages, each of 16 addresses.

Table below shows the SPI page vs. macro function distribution.

Note:

Assumptions on solenoid channel status.

Solenoid Channel State: (DISABLED, TRISTATED, ACTIVE);

DISABLED: Channel inactive, Driver Hi impedance, no diagnosis available.

TRISTATED: Channel enabled, Driver Hi impedance, Thermal/OFF diagnosis available.

ACTIVE: Channel enabled, Driver operating according PWM, Thermal/ON diagnosis available.

During power on sequence, all solenoid channels are in DISABLED state. At the end of power on sequence,

channel status is controlled by EN_DR pin status (0 => DISABLED) and SPI registers (SERVENA and

SOLENDRV).

In the following tables RES1 reset event has to be intended as the combination of internal events triggering reset

pin low and RES1 trigger from external command; unused bits for SDO data fields are reported as 0 in the data

out frame.
