# SBC

From GbdevWiki

**This is an article about the GB-Z80 CPU.**

Opcodes:

**Arithmetic and logical:** ADD - ADD (16-bit) including LD HL,SP+nn - ADC - AND - CP - CPL - DAA - DEC - DEC and INC (16-bit) - INC - **SBC** - SUB - OR - XOR

**Conditional:** CALL - JP - JR - RET

**Load:** LD (8-bit) - LD (16-bit)

**Extended Set:** BIT - RES - RL - RLC - RR - RRC - SET - SLA - SRA - SRL - SWAP

The operand, along with the Carry flag (C in the F register) is subtracted from the contents of the Accumulator, and the result is stored in the Accumulator.
