SOPR—Set the Output Port Bits (OPR)
SOPR[7:0]—Ones in the byte written to this register will cause the corresponding bit positions in the OPR to set to 1. Zeros have no effect. This
allows software to set individual bits with our keeping a copy of the OPR bit configuration.
ROPR—Reset Output Port Bits (OPR)
ROPR[7:0]—Ones in the byte written to the ROPR will cause the corresponding bit positions in the OPR to set to 0. Zeros have no effect. This
allows software to reset individual bits with our keeping a copy of the OPR bit configuration.
OPR Output Port Register
The output pins (OP pins) drive the compliment of the data in this register as controlled by SOPR and ROPR.
