Pins Used in SPI Bootmode SIGNAL NAME PIN NO. TYPE SPI[0]_SCS[0] G29 I/O SPI[0]_D[0] (MISO) J28 I/O SPI[0]_D[1] (MOSI) J27 I/O SPI[0]_SCLK N24 I/O 4.2.6 Ethernet PHY Mode Selection When the EMAC bootmode is selected, via the BTMODE[4:0] pins (see Table 4-1), Table 4-7 shows the sampled value of BTMODE[9:8] pins and the Ethernet PHY Mode selection. Table 4-9 shows the signal names (pin functions) and the associated pin numbers selected in each particular EMAC mode. Table 4-7.
