PNOTn – Port NOT Register
This register allows to invert a bit Pn_m of the port register Pn without directly
writing to Pn (n = 0 to 5, 8).
Access
Writing in 16-bit units is the only form of access. The register is always read as
0000
H
.
Address
Refer to Table 2-7, Port Group Configuration Registers.
Initial value
