CLC is a 65x instruction that clears the carry flag.

The 6502 lacks an add-without-carry instruction, so it is important to make sure the carry flag is clear before doing an ADC or else the sum will be one too great.

No other flags are affected.

Syntax

CLC

One of the first instructions a SNES game runs after coming out of reset is often a CLC so that XCE can switch to native mode.
