---|---|---|---|---|
7-0 | PxSEL | R/W | 0h | Port function selection. Each bit corresponds to one channel on Port x. The values of each bit position in PxSEL2 and PxSEL are combined to specify the function. For example, if P1SEL2.5 = 1 and P1SEL.5 = 0, then the secondary module function is selected for P1.5. See PxSEL2 for the definition of each value. Note: NOTE: If P2.6 and P2.7 are multiplexed with XIN and XOUT, respectively, the reset value of P2SEL is C0h. If XIN and XOUT have dedicated pins, the reset value of P2SEL is 00h. |
