System Integration Unit (SIU)MPC5566 Microcontroller Reference Manual, Rev. 26-96 Freescale Semiconductor6.3.1.132 Pad Configuration Register 229 (SIU_PCR229)The SIU_PCR229 register controls the enabling/disabling and drive strength of CLKOUT. CLKOUT isenabled and disabled by setting and clearing the OBE bit. CLKOUT is enabled during reset.Figure 6-133. CLKOUT Pad Configuration Register (SIU_PCR229)6.3.1.133 Pad Configuration Register 230 (SIU_PCR230)The SIU_PCR230 register controls the slew rate of RSTOUT.Figure 6-134. RSTOUT Pad Configuration Register (SIU_PCR230)6.3.1.134 Pad Configuration Register 231–255 (SIU_PCR231–SIU_PCR255)The SIU_PCR231–SIU_PCR255 registers are not implemented in this device.6.3.1.135 Pad Configuration Register 256 (SIU_PCR256)The SIU_PCR256 register controls the function, direction, and electrical attributes of CAL_CS[0].Figure 6-135.
