GPIO MASK0 addressOffset = 0x2080

These registers affect writing and reading the MPORT registers. Zeroes in these registers enable reading and writing; ones disable writing and result in zeros in corresponding positions when reading.

Table 1. GPIO registerName = MASK0 addressOffset = 0x2080
Bit Symbol Description Reset value Access
17:0 MASKP0 Controls which bits corresponding to PIO0_n are active in the P0MPORT register (bit 0 = PIO0_0, bit 1 = PIO0_1, ..., bit 17 = PIO0_17). 0 = Read MPORT: pin state; write MPORT: load output bit. 1 = Read MPORT: 0; write MPORT: output bit not affected. 0 R/W
