GPIO19 ~ GPIO18 output mode enable
1 = enable
0 = disable
NOTE: Output mode enable bits are valid only when bit
PT1CFG1-0 is configured as general purpose I/O mode.
Each port pin can be enabled individually by setting the
corresponding control bit.

DESCRIPTION
-
PORT1 data output value
Writing data to this register will reflect the data value on the
corresponding port1 pin when it is configured as general purpose
output pin. And writing data to reserved bits is not effective.
