MSP430I2041: How many instruction cycles for BIS.W

Part Number: MSP430I2041

Support,

Sorry if this obvious but how many cycles does "SD24CCTL0 |= SD24SC;" take?  I would think it is '1' but I'm not 100% sure when looking at the disassembly.  The whole line becomes 4 addresses - opcodes + operands.

95         SD24CCTL0 |= SD24SC; // Set bit to start conversion
820a:    D3A2 0102 BIS.W #2,&SD24_A4_SD24CCTL0

96         __bis_SR_register(LPM0_bits | GIE); // Enter LPM0 w/ interrupts
820e:    D032 0018 BIS.W #0x0018,SR
