If the port pins are not bonded out in the chosen package the user should initialize the registers to be inputs
with enabled pull resistance to avoid excess current consumption. This applies to the following pins:

Function 1
Pin Name
The Port E output buffer enable signal control at reset is determined by the PEAR register and is mode dependent. For
example, in special test mode RDWE = LSTRE = 1 which enables the PE[3:2] output buffers and disables the pull-ups. Refer
to the S12 MEBI block description chapter for PEAR register details.
