6.7 Port E
M68HC11K Family
MOTOROLA
NOTE:
Alternate Pin Function:
Address: $000A
Port E, PE[7:0], is the only port that functions as input only, and its pins
are configured as high-impedance inputs out of reset. It also serves as
the analog input for the analog-to-digital converter when this function is
enabled by software (see
Converter).
PORT E should not be read during the sample portion of an A/D
conversion.
