16.6.15.157Pad Configuration Register 340 (SIU_PCR340)
NOTE
Unlike other pad configuration registers (PCRs), which control the function
and electrical characteristics of one pin, this register controls the function
and electrical characteristics for a group of pins on the Calibration bus.

16.6.15.158Pad Configuration Register 341 (SIU_PCR341)
NOTE
Unlike other pad configuration registers (PCRs), which control the function
and electrical characteristics of one pin, this register controls the electrical
characteristics for a group of pins on the Calibration bus.

1
In cases where an I/O function can be either an input or an output, I/O direction is specified using the IBE and OBE
bits. Set IBE = 1 for input or OBE = 1 for output.
2
For I/O functions that change direction dynamically, such as the external data bus, switching between input and
output is handled internally and the IBE and OBE bits are ignored.
