6.3.1.12.62 Pad Configuration Register 106 (SIU_PCR106)
The SIU_PCR106 register controls the pin function, direction, and static electrical attributes of the
PCSB[1]_PCSD[0]_GPIO[106] pin.
Figure 6-74. PCSB[1]_PCSD[0]_GPIO[106] Pad Configuration Register (SIU_PCR106)
Refer to Table 6-16 for bit field definitions.
6.3.1.12.63 Pad Configuration Register 107 (SIU_PCR107)
The SIU_PCR107 register controls the pin function, direction, and static electrical attributes of the
PCSB[2]_SOUTC_GPIO[107] pin.

When configured as PCSB[1], the OBE bit has no effect. When configured as PCSD[0], 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 PCSD[0] in slave operation, set the IBE bit to 1. When configured as PCS in master operation 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.
