Detailed Description

32-bit SPI frame structure for TLE92466ED communication

The TLE92466ED uses 32-bit SPI frames with the following format:

MOSI (Write) Frame:

*  Bits 31-24 | Bits 23-17 | Bit 16 | Bits 15-0
* ------------+------------+--------+-----------
*  CRC (8-bit)| Address(7) |  R/W   | Data (16)
* 

MISO (Reply) Frame:

*  Bits 31-24 | Bits 23-22 | Bits 21-17 | Bit 16 | Bits 15-0
* ------------+------------+------------+--------+-----------
*  CRC (8-bit)| Reply Mode | Status (5) | R/W    | Data (16)
* 

Member Function Documentation

make_read()

static constexpr SPIFrame TLE92466ED::SPIFrame::make_read ( uint16_t addr )

inlinestaticconstexprnoexcept

Construct read frame (without CRC - must be calculated separately)

Parameters

addr	Register address (10-bit actual address)

Returns

SPIFrame configured for read operation (CRC = 0)

make_write()

static constexpr SPIFrame TLE92466ED::SPIFrame::make_write ( uint16_t addr, uint16_t data )

Construct write frame (without CRC - must be calculated separately)

Parameters

addr	Register address (10-bit actual address)
data	Data word to write (16-bit)

Returns

SPIFrame configured for write operation (CRC = 0)
