System Integration Unit (SIU)MPC5566 Microcontroller Reference Manual, Rev. 26-56 Freescale Semiconductor6.3.1.66 Pad Configuration Register 100 (SIU_PCR100)The SIU_PCR100 register controls the function, direction, and electrical attributes ofPCSA[4]_SOUTD_GPIO[100]. This register allows selection of the PCSA[4], SOUTD, and GPIOfunctions.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 forPCSA[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 ofPCSA[5]_PCSB[3]_GPIO[101]. This register allows selection of the PCSA[5], PCSB[3] and GPIOfunctions.Figure 6-68.

When configured as GPDO, set the OBE to 1.IBE33 When PCSA[4] or SOUTD is configured for slave operation, set the IBE bit to 1. When the pad is configured as an output, setthe IBE bit to 1 to show the pin state in the GPDI register. Clear the IBE bit to 0 to reduce power consumption. When configuredas GPDI, set the IBE bit to 1.0 0 ODE HYS SRC WPE WPSWRESET: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1Table 6-66.
