Read/write a single bit (MCP23018)

[mister_e]

Bitwise operation & masks

assuming VarA = %11110000

If i want to set a single bit, say Bit0, I can do it like
VarA.0=1

OR doing it with mask
VarA = VarA | %00000001

If you want to clear a bit, says bit 7, then you use
VarA.7=0

OR

VarA = VarA & %01111111

If I want to READ a single bit, say bit 2, then, I can use
AnotherVar = VarA.2
