I was just referencing the 6502 opcodes page concerning the BIT instruction and noticed that is says "S and V flags" rather then "N and V flags". I'm not sure who maintains this page do I'm posting this here.

Quote:
BIT (test BITs)
Affects Flags: N V Z

MODE SYNTAX HEX LEN TIM
Zero Page BIT $44 $24 2 3
Absolute BIT $4400 $2C 3 4

BIT sets the Z flag as though the value in the address tested were ANDed with the accumulator. The S and V flags are set to match bits 7 and 6 respectively in the value stored at the tested address.
