TE0745 module supports different boot modes which are configurable by the control line 'BOOTMODE' and 'BOOTMODE_1'. The line 'BOOTMODE' is available on B2B connector pin J2-133, the line 'BOOTMODE_1' is connected to the System Controller CPLD on bank 1, pin 21 (permanent logic high in standard SC-CPLD firmware).The boot mode selection will be set by the Zynq's PS MIO pins MIO3...MIO5.
