Function mcp2515_get_message appears the following instruction:

 uint32_t i1 = (uint32_t) spi_putc(0xff),
          i2 = (uint32_t) spi_putc(0xff),
          i3 = (uint32_t) spi_putc(0xff),
          i4 = (uint32_t) spi_putc(0xff);

This instruction is used to fetch data used for determining the message id. Supposing the 32 bit source data contains Hex 0xAA3A6060, which values will appear in i1, i2, i3, i4?

Any help will be much appreciated.

    Is the "32 bit source" big or little endian? – Majenko Aug 13 at 13:11
