Product Specification (V1.0) 07.26.2005
(This specification is subject to change without further notice)
Bit 3 ( EXIE3 ) :
External INT3 pin Interrupt enable bit.
EXIE3 = “0” :
disable EXIF3 interrupt
EXIE3 = “1” :
enable EXIF3 interrupt
Bit 2 ( TCIE4 )
:
Timer/Counter 4 Interrupt enable bit.
TCIE4 = “0” :
disable TCIF4 interrupt
TCIE4 = “1” :
enable TCIF4 interrupt
Bit 1 ( SPIE ) :
SPI Interrupt enable bit.
SPIE = “0” :
disable SPIF interrupt
SPIE = “1” :
enable SPIF interrupt
Bit 0 ( TCIE3 ) :
Timer/Counter 3 Interrupt enable bit.
TCIE3 = “0” :
disable TCIF3 interrupt
TCIE3 = “1” :
enable TCIF3 interrupt
Individual interrupt is enabled by setting its associated control bit in the IMR1
to "1".
Global interrupt is enabled by the ENI instruction and is disabled by the DISI
instruction.
IMR1 register is both readable and writable.
IMR2
Interrupt Mask Register 2( Address: 0Fh )

URIE = “1” :
enable RBFF interrupt
Bit 4 ( UTIE ) :
UART transmit mode interrupt enable bit.
UTIE = “0” :
disable TBEF interrupt
UTIE = “1” :
enable TBEF interrupt
