6.3.1.62 Pad Configuration Register 100 (SIU_PCR100)
The SIU_PCR100 register controls the function, direction, and electrical attributes of
PCSA[4]_SOUTD_GPIO[100]. This register allows selection of the SOUTD, and GPIO functions.
Figure 6-61. PCSA[4]_SOUTD_GPIO[100] Pad Configuration Register (SIU_PCR100)
Refer to Table 6-19 for bit field definitions. Table 6-56 lists the PA fields for
PCSA[4]_SOUTD_GPIO[100].
6.3.1.63 Pad Configuration Registers 101 (SIU_PCR101)
The SIU_PCR101 register controls the function, direction, and electrical attributes of
PCSA[5]_PCSB[3]_GPIO[101]. This register allows selection of the PCSB[3] and GPIO functions.

The PCSA[4] function is not available on the device. Do not select 0b01 or 0b11 for the PA field.
OBE

2
When configured as SOUTD, the OBE bit has no effect. When configured as GPDO, set the OBE to 1.
IBE
3
3
When SOUTD is configured for 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.
