34 / 61 page  USB84604 DS60001295C-page 34 2014-2016 Microchip Technology Inc. 7.1.8 JEDEC-ID READ EXAMPLE To perform a JEDEC-ID command, the device writes 0x9F into the first byte of the SPI_CMD_BUF. The length of the transfer is 4 bytes. The device first drives SPI_CE_N low, then SPI_DO is output with 8 bits of the command, followed by the 24 bits of dummy bytes (due to the length being set to 4). When the transfer is complete, SPI_CE_N goes high. After the first byte, the data on SPI_DI is clocked into the SPI_RSP_BUF. At the end of the command, there are three valid bytes in the SPI_RSP_BUF. In this example, 0xBF, 0x25, 0x8E. FIGURE 7-4: SPI COMMAND ONLY SEQUENCE SPI_CE_N SPI_CLK 12 3 4 05 7 6 SPI_DO SPI_DI Command MSB HIGH IMPEDANCE |
