6.3.1.60 Pad Configuration Register 94 (SIU_PCR94)
The SIU_PCR94 register controls the function, direction, and electrical attributes of
SINA_PCSC[2]_GPIO[94]. This register allows selection of the SINA, PCSC[2] and GPIO functions.
Figure 6-61. SINA_PCSC[2]_GPIO[94] Pad Configuration Register (SIU_PCR94)
Refer to Table 6-19 for bit field definitions. Table 6-60 lists the PA fields for SINA_PCSC[2]_GPIO[94].
6.3.1.61 Pad Configuration Register 95 (SIU_PCR95)
The SIU_PCR95 register controls the function, direction, and electrical attributes of
SOUTA_PCSC[5]_GPIO[95]. This register allows selection of the SOUTA, PCSC[5] and GPIO[95]
functions.

The SINA function is available on the MPC5566 only.
OBE

When configured as SINA or PCSC[2], the OBE bit has no effect. When configured as GPDO, set the OBE bit to 1.
IBE

3
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.
