Chapter 23 DQ256 Port Integration Module (S12XDQ256PIMV2)
23.0.5.11 S12X_EBI Ports, BKGD, VREGEN Pin Pull-up Control Register (PUCR)
Read: Anytime in single-chip modes.
Write: Anytime, except BKPUE which is writable in special test mode only.
This register is used to enable pull-up devices for the associated ports A, B, C, D, E, and K. Pull-up devices
are assigned on a per-port basis and apply to any pin in the corresponding port currently configured as an
input.
