6.3.1.72 Pad Configuration Register 106 (SIU_PCR106)
The SIU_PCR106 register controls the function, direction, and electrical attributes of
PCSB[1]_PCSD[0]_GPIO[106].
Figure 6-73. PCSB[1]_PCSD[0]_GPIO[106] Pad Configuration Register (SIU_PCR106)
Refer to Table 6-19 for bit field definitions. Table 6-72 lists the PA fields for
PCSB[1]_PCSD[0]_GPIO[106].
6.3.1.73 Pad Configuration Register 107 (SIU_PCR107)
The SIU_PCR107 register controls the function, direction, and electrical attributes of
PCSB[2]_SOUTC_GPIO[107].

PA OBE
1
1
When configured as PCSD[0], set the OBE bit to 1 for master operation, or clear to 0 for slave operation.
When configured as PCSB[1], the OBE bit has no effect. When configured as GPDO, set the OBE bit to 1.
IBE
2
2
When configured as PCSD[0] in slave operation, set the IBE bit to 1. When the pad is configured as an output, set the IBE bit
to 1 to show the pin state in the GPDI register. Clear the IBE bit to 0 to reduce power consumption. When configured as GPDI,
set the IBE bit to 1.
