PORT UA[0:1] not working as expected

Surely i´m missing something, but when trying to use UA port as digital inputs on the MCF52211CAF80 the two lower [1:0] bits (pins 8 and 7) only read 1´s (the PUAPAR and DDRUA are supposely correct). These port I/O´s appear to weak pull-down, while [3:2] are pulled-up (?!). Any suggestion?
