6.3.1.63 Pad Configuration Registers 97 (SIU_PCR97)
The SIU_PCR97 registers control the function, direction, and electrical attributes of
PCSA[1]_PCSB[2]_GPIO[97]. This register allows selection of the PCSA[1], PCSB[2] and GPIO
functions.
Figure 6-64. PCSA[1]_PCSB[2]_GPIO[97] Pad Configuration Register (SIU_PCR97)
Refer to Table 6-19 for bit field definitions. Table 6-63 lists the PA fields for
PCSA[1]_PCSB[2]_GPIO[97].
6.3.1.64 Pad Configuration Register 98 (SIU_PCR98)
The SIU_PCR98 register controls the function, direction, and electrical attributes of
PCSA[2]_SCKD_GPIO[98]. This register allows selection of the PCSA[2], SCKD, and GPIO functions.

The PCSA[1] function is available on the MPC5566 only.
OBE

2
When configured as PCSA[1] or PCSB[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.
