6.3.1.12.58 Pad Configuration Register 102 (SIU_PCR102)
The SIU_PCR102 register controls the pin function, direction, and static electrical attributes of the
SCKB_PCSC[1]_GPIO[102] pin.
Figure 6-70. SCKB_PCSC[1]_GPIO[102] Pad Configuration Register (SIU_PCR102)
Refer to Table 6-16 for bit field definitions.
6.3.1.12.59 Pad Configuration Register 103 (SIU_PCR103)
The SIU_PCR103 register controls the pin function, direction, and static electrical attributes of the
SINB_PCSC[2]_GPIO[103] pin.

When configured as SCKB, set the OBE bit to 1 for master operation, and clear it to 0 for slave operation. When configured as
GPO, set the OBE bit to 1.

When configured as SCKB in slave operation set the IBE bit to 1. When configured as SCKB in master operation 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.
