procedure TWI_Init(clock : dword);

Nothing.

Initializes TWI with desired clock (refer to device data sheet for correct values in
respect with Fosc). Needs to be called before using other functions of TWI Library.

You don’t need to configure ports manually for using the module; library will take
care of the initialization.

Library requires MSSP module on PORTB or PORTC.

TWI_Init(100000);

function TWI_Busy() : byte;

Returns 0 if TWI start sequnce is finished, 1 if TWI start sequnce is not finished.

Signalizes the status of TWI bus.

TWI must be configured before using this function. See TWI_Init.
