FUNCTION If condition true then program execution continues at:
(PC) + offset.
PC value is instruction address more two.
Offset is the relative value in bytes which separate Bcc instruction of mentioned label.

Condition code 'cc' specifies one of the following:
0000FFalseZ = 1
0001T TrueZ = 0
0010HIHIghC + Z = 0
0011LSLow or SameC + Z = 1
0100CCCarry ClearC = 0
0101CSCarry SetC = 1
0110NENot EqualZ = 0
0111EQEQualZ = 1
1000VCoVerflow ClearV = 0
1001VSoVerflow SetV = 1
1010PLPLusN = 0
1011MIMInusN = 1
1100GEGreater or EqualN (+) V = 0
1101LTLess ThanN (+) V = 1
1110GTGreater ThanZ + (N (+) V) = 0
1111LELess or EqualZ + (N (+) V) = 1
