45 / 151 page  5.10 SPI MOSI/MISO list The following paragraph contains the SPI MOSI and MISO list. Each frame consists of 32 bits with odd parity. Protocol is out of frame. The following table contains links to SPI commands that can be sent on MOSI line, along with their description. The corresponding answers issued by L9945 on MISO line are also described and linked on the right columns. Note: All MISO default values have been scanned performing read only requests ("R/W" = 1). Table 30. SPI MOSI list MOSI Request Answer MISO COMMAND 0 Spread spectrum and diagnostic enable,OUT1-8 control, input selection and protection disable Spread spectrum and diagnostic enable, input selection, protection disable and output voltage status RESPONSE 0 COMMAND 1 OUT1 configuration and H-Bridge 1 diagnostic time OUT1 configuration and H-Bridge 1 diagnostic time RESPONSE 1 COMMAND 2 OUT2 configuration, H-Bridge 1 current limitation timing, BCF selection OUT2 configuration, H-Bridge 1 current limitation timing, BCF selection RESPONSE 2 COMMAND 3 OUT3 configuration, H-Bridge 1 current limitation enable and active freewheeling, gate charge/ discharge current override OUT3 configuration, H-Bridge 1 current limitation enable and active freewheeling, gate charge/ discharge current override RESPONSE 3 COMMAND 4 OUT4 configuration, P&H1 configuration, H-Bridge 1 enable OUT4 configuration, P&H1 configuration, H-Bridge 1 enable RESPONSE 4 COMMAND 5 OUT 5 configuration and H-Bridge 2 diagnostic time OUT 5 configuration and H-Bridge 2 diagnostic time RESPONSE 5 COMMAND 6 OUT6 configuration, H-Bridge 2 current limitation timing OUT6 configuration, H-Bridge 2 current limitation timing RESPONSE 6 COMMAND 7 OUT7 configuration, H-Bridge 2 current limitation enable and active freewheeling OUT7 configuration, H-Bridge 2 current limitation enable and active freewheeling RESPONSE 7 COMMAND 8 OUT8 configuration, P&H2 configuration, H-Bridge 2 enable OUT8 configuration, P&H2 configuration, H-Bridge 2 enable RESPONSE 8 COMMAND 9 Diagnostic read and diagnostic pulses H-Bridge1-2 current limitation latches and channels diagnostic status RESPONSE 9 COMMAND 10 BIST request and CC enable BIST & HWSC result and device status RESPONSE 10 COMMAND 11 Channel 1-4 control signal integrity Channel 1-4 control signal integrity RESPONSE 11 COMMAND 12 Channel 5-8 control signal integrity Channel 5-8 control signal integrity RESPONSE 12 COMMAND 13 Device status, battery and temperature monitor Device status, battery and temperature monitor RESPONSE 13 Note: ΔT = TjFET: Tj TjFET = junction temperature of the external FET Tj = junction temperature of L9945.
