Arguments
- const Bit[4] D: Destination bank.
- const Bit[4] S: Source bank.

Description
Sets the nth bit in the “Dest” location, where n is a number between 0-7 supplied in “Bit”. A value of zero in “Bit” will reset the least significant bit. If the Source Bank is 0 then the bit to be set is taken from “Bit”. If the Source Bank is an 8 bit bank, then the “Bit†is the address in that bank where the operand is.
