Bit 3 ( TBIE ) :
Time base timer interrupt enable bit.
TBIE = “0” :
disable TBIF interrupt
TBIE = “1” :
enable TBIF interrupt
Bit 2 ( EXIE1 ) :
External INT 1 Interrupt enable bit.
EXIE1 = “0” :
disable EXIF1 interrupt
EXIE1 = “1” :
enable EXIF1 interrupt
Bit 0 ( TCIE0 ) :
TCC Interrupt enable bit.
TCIE0 = “0” :
disable TCIF0 interrupt
TCIE0 = “1” :
enable TCIF0 interrupt
Individual interrupt is enabled by setting its associated control bit in the IMR2
to "1".
Global interrupt is enabled by the ENI instruction and is disabled by the DISI
instruction.
IMR2 register is both readable and writable.
