The LB_POR_CFG_BOOT_ECC_DIS function will be selected on the TSEC_MDC pin whenever HRESET is
asserted; the pin will act as TSEC_MDC at all other times. The reset block will sample this signal on PORESET
negation only; the sampled value is then passed to the eLBC controller to enable/disable ECC checking during boot
time. An internal pull-down resistor has been added to this pad to enable the boot-time ECC checking by default. A
pull-up resistor, via a three-state buffer, is needed during HRESET assertion period to disable ECC checking during
boot time.

Must be connected to a 10K ±1% precision resistor if using the integrated USB PHY through the UTMI.
Table 3-2 lists the signals in alphabetical order.
