6.3.1.12.48 Pad Configuration Register 92 (SIU_PCR92)
The SIU_PCR92 register controls the pin function, direction, and static electrical attributes of the
RXDB_PCSD[5]_GPIO[92] pin.
Figure 6-60. RXDB_PCSD[5]_GPIO[92] Pad Configuration Register (SIU_PCR92)
Refer to Table 6-16 for bit field definitions.
6.3.1.12.49 Pad Configuration Register 93 (SIU_PCR93)
The SIU_PCR93 register controls the pin function, direction, and static electrical attributes of the
SCKA_PCSC[1]_GPIO[93] pin. The SCKA function is not available in the MPC5553 (this register allows
selection of the PCSC[1] and GPIO functions).

When configured as RXDB or PCS, the OBE bit has no effect. When configured as GPO, set the OBE bit to 1.
IBE

2
When configured as RXDB or PCS or GPO, set the IBE bit to 1 to reflect the pin state in the corresponding GPDI register. Clear
the IBE to 0 to reduce power consumption. When configured as GPI, set the IBE bit to 1.

When configured as SCKA, set the OBE bit to 1 for master operation, or clear the OBE bit to 0 for slave operation. When
configured as PCS, the OBE bit has no effect. When configured as GPO, set the OBE bit to 1.

When configured as SCKA in slave operation, set the IBE bit to 1. When configured as SCKA in master operation, PCS, or
GPO, set the IBE bit to 1 to reflect the pin state in the corresponding GPDI register. Clear the IBE to 0 to reduce power
consumption. When configured as GPI, set the IBE bit to 1.
