Reset value:
Reset value:
Reset value:
Interrupt priority bit PTWSI = 1 assigns high interrupt priority
Interrupt priority bit PTWSI = 0 assigns low interrupt priority
Interrupt Enable I Register (IE1, $A9)
Interrupt enable bit ETWSI = 1 enables the TWSI interrupt
Interrupt enable bit ETWSI = 0 disables the TWSI interrupt
Interrupt Flag Register (IFR, $AA)
Interrupt flag bit TWSIIF will be set to 1 when TWSI interrupt occurs. Interrupt flag bit TWSIIF will be clear to 0 if TWSI
interrupt subroutine executed.
