Figure 6-45. TEA_GPIO[71] Pad Configuration Register (SIU_PCR71)
Refer to Table 6-19 for bit field definitions. Table 6-45 lists the PA fields for TEA_GPIO[71].
6.3.1.45 Pad Configuration Register 72 (SIU_PCR72)
The SIU_PCR72 register controls the function, direction, and electrical attributes of
BR_FEC_MDC_GPIO[72]. This register allows selection of the GPIO functions.
Figure 6-46. To use the BR function, the PA field must be set to BR before EBI_MCR[EXTM] is set.
BR_FEC_MDC_GPIO[72] Pad Configuration Register (SIU_PCR72)
Refer to Table 6-19 for bit field definitions. Table 6-46 lists the PA field for BR_FEC_MDC_GPIO[72].

1
When configured as TEA, the OBE bit has no effect. When configured as GPDO, set the OBE bit to 1.
IBE
2
2
When the pad is configured as an output, set the IBE bit to 1 to show the pin state in the GPDI register.
Clear the IBE bit to 0 to reduce power consumption. When configured as GPDI, set the IBE bit to 1.
DSC ODE

When configured as TEA and external master operation is enabled, clear the ODE bit to 0.
HYS
