Product Specification (V1.0) 10.03.2006
(This specification is subject to change without further notice)
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.
The IMR1 register is both readable and writable.
IMR2
− Interrupt Mask Register 2( Address: 0Fh )
