M7101 Original Pin Definition Setting - Acer Extensa 61X Service Manual

When offset 0F6h, D5=1 and offset 0FBh, D7=1; GPIOB[7:0] and GPIOA[7:0] output some clocks
for testing. The clocks are OTCOUNT, O16K, TCLK2, TCLK3, O128HZ, O16HZ, O8HZ, O4HZ,
O2HZ, O1Hz, ELCOUNT, DZCOUNT, SLCOUNT, RICOUNT, LBCOUNT[1:0].
