5.1.2 ClearBit – Clears the specified bit

Prototype

sub procedure ClearBit(dim byref Reg as byte, dim Bit as byte)

Description Clears <Bit> of register <Reg>. Any SFR (Special Function Register) or variable of byte type can pass as valid

variable parameter, but constants should be in range [0..7].

Example

ClearBit(PORTC,7) ' clear bit RC7

5.1.3 TestBit – Tests the specified bit

Prototype

sub function TestBit(dim byref Reg as byte, dim Bit as byte) as byte

Description Tests <Bit> of register <Reg>. If set, returns 1, otherwise 0. Any SFR (Special Function Register) or variable of

byte type can pass as valid variable parameter, but constants should be in range [0..7].

Example

TestBit(PORTA,2)

' returns 1 if PORTA bit RA2 is 1, returns 0 otherwise

5.1.4 Lo – Extract one byte from the specified parameter
