6.3.1.66 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 PCSA[4], SOUTD, and GPIO
functions.
Figure 6-67. PCSA[4]_SOUTD_GPIO[100] Pad Configuration Register (SIU_PCR100)
Refer to Table 6-19 for bit field definitions. Table 6-66 lists the PA fields for
PCSA[4]_SOUTD_GPIO[100].
6.3.1.67 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 PCSA[5], PCSB[3] and GPIO
functions.

The PCSA[4] function is available on the MPC5566 only.
OBE

When configured as PCSA[4] or SOUTD, the OBE bit has no effect. When configured as GPDO, set the OBE to 1.
IBE

3
When PCSA[4] or 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.
