NOTE:
Signals shown in bold are not available in the 80 pin package.
NOTE:
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:
(80QFP): Port A[7:0], Port B[7:0], Port E[6,5,3,2], Port K[7:0], Port U[7:4]

NOTES
:
1. 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 Guide for PEAR register details.
