6.3.1.12.60 Pad Configuration Register 104 (SIU_PCR104)
The SIU_PCR104 register controls the pin function, direction, and static electrical attributes of the
SOUTB_PCSC[5]_GPIO[104] pin.
Figure 6-72. SOUTB_PCSC[5]_GPIO[104] Pad Configuration Register (SIU_PCR104)
Refer to Table 6-16 for bit field definitions.
6.3.1.12.61 Pad Configuration Register 105 (SIU_PCR105)
The SIU_PCR105 register controls the pin function, direction, and static electrical attributes of the
PCSB[0]_PCSD[2]_GPIO[105] pin.

When configured as SOUTB 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.
