6.3.1.12.64 Pad Configuration Register 108 (SIU_PCR108)
The SIU_PCR108 register controls the pin function, direction, and static electrical attributes of the
PCSB[3]_SINC_GPIO[108] pin.
Figure 6-76. PCSB[3]_SINC_GPIO[108] Pad Configuration Register (SIU_PCR108)
Refer to Table 6-16 for bit field definitions.
6.3.1.12.65 Pad Configuration Register 109 (SIU_PCR109)
The SIU_PCR109 register controls the pin function, direction, and static electrical attributes of the
PCSB[4]_SCKC_GPIO[109] pin.

When configured as PCS or SINC 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 SCKC, set the OBE bit to 1 for master operation, and clear it 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 SCKC in slave operation, set the IBE bit to 1. When configured as PCS or SCKC 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.
