MPC5604B/C Microcontroller Reference Manual, Rev. 8
Freescale Semiconductor 339
NOTE
16/32-bit access is supported.
In addition to the bit map above, the following Table 19-11 describes the PCR depending on the pad type
(pad types are defined in the “Pad types” section of this reference manual). The bits in shaded fields are
not implemented for the particular I/O type. The PA field selecting the number of alternate functions may
or may not be present depending on the number of alternate functions actually mapped on the pad.
Offsets: Base + 0x0040 (PCR0)(123 registers)
Base + 0x0042 (PCR1)
...
Base + 0x0130 (PCR122)
Access: User read/write
