Generic Control Slave Software Description

Generic Control of the MC33912 device is through the SPI channel. Control data is transported to the MCU by FreeMASTER 
protocol or LIN protocol, as well as data from the A/D converter and MCU memory. 

The units that are transported in a LIN diagnostic frame are called PDU’s (Packet Data Unit). A PDU used for Generic Control of 
the device is a Single Frame message based on the User Defined Diagnostics specification. The diagnostic format sends a fixed 
master request frame with eight data bytes provided. This is used to issue specific Generic Control fixed frames.

Messages issued by the master are called requests, and messages issued by the slave are called responses. Requests are 
always sent in master request frames and responses are always sent in slave response frames. The Master request frame has 
a fixed identifier, 60 (0x3C) and a fixed size (8 bytes). The Slave response frame has a fixed identifier, 61 (0x3D) and a fixed size 
(8 bytes). 

The meaning of each byte in a PDU is defined in the following sections.

6.2.1 Generic Control PDU Structure

The Generic Control PDU structure is described in this section; see

NAD

NAD is the address of the slave node being addressed by a request. NAD is also used to indicate the source of the 
response.
Generic Control is uses Free NAD values, meaning that the NAD value must be selected from the range 128 (0x80) 
- 255 (0xFF), and not to be interpreted as a diagnostic. For the KIT33912EVME NAD - 160 (0xA0) is used.

CMD

CMD is a command being sent by the master in a request to be interpreted by the slave. CMD is also used to 
interpret the status data in a response.
CMD code:

0 = SPI - read and write SPI data registers through the SPI channel
1 = PWM - write a value to the MCU pulse width modulation registers
2 = ADC - read data from the A/D converter the MCU registers
3 = TOOLS_TO_MCU - special commands to change the MCU state and activity
4 = TOOLS_TO_PC - special commands to read the MCU state and activity
