This says:
"The SDA and SCL lines can only be PULLED low. They cannot be DRIVEN high.
To make them high the device just releases the line. "
In:
inline void clkhigh()
{
P2OUT |= CLKBIT;
writedigit(2, '1');
}
try
P2DIR &= ~CLKBIT;
In releaseDataHigh() similary.
In slave TimerA interrupt
try save initial value of P2IFG in variable and next test this, not P2IFG
