SOPR – Set Bits in the OPR
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 without keeping a copy of the OPR bit configuration.
ROPR – Reset Bits in the OPR
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 bits in the OPR register are controlled by the use of the SOPR and ROPR commands. The output pins (OP pins) drive the compliment of
the data stored in this register.
