0x014 SYSINT – System Interrupts and Interrupt Enables (Continued)
BIT
NAME
TYPE
RESET
FUNCTION
1
LLCINT1
RU
0
Link interrupt 1 This bit is set by hardware to indicate that an assigned
interrupt in the upper doublet of the LINT register has been triggered.
This bit is cleared when the interrupt is cleared in the LINT register.
0
LLCINT0
RU
0
Link interrupt 0 This bit is set by hardware to indicate that an assigned
interrupt in the lower doublet of the LINT register has been triggered.
This bit is cleared when the interrupt is cleared in the LINT register.

RSVD
R0
0
Reserved – A write to this location has no effect. A read returns 0s.
19
SERIALDONEINTEN
RW
1
Two-wire serial interface done interrupt enable – When set to 1
MCIFINT.SerialDoneInt is an interrupt source. When set to 0
MCIFINT.SerialDoneInt is not an interrupt source. This interrupt is
enabled at reset to allow the microcontroller to determine
completion of EEPROM download without accessing the device.
18
SERIALERRINTEN
RW
0
Two-wire serial interface error interrupt enable When set to 1
MCIFINT.SerialERRINT is an interrupt source. When set to 0
MCIFINT.SerialERRINT is not an interrupt source.
17
RSVD
R0
0
Reserved – A write to this location has no effect. A read returns 0.
16
MCERRINTEN
RW
0
Microcontroller error interrupt enable
When set to 1 MCIFINT.MCERRINT is an interrupt source.
When set to 0 MCIFINT.MCERRINT is not an interrupt source.

Reserved – A write to this location has no effect. A read returns 0s.
3
SERIALDONEINT
RCU
0
Two-wire serial interface done – This interrupt is generated when
EEPROM download is complete or no EEPROM is detected on
power up and the associated enable bit is set. Write 1 to clear.
2
SERIALERRINT
RCU
0
Two-wire serial interface error – This interrupt is generated when
an error is detected on the two-wire serial interface and the
associated enable bit is set. Write 1 to clear.
1
RSVD
R0
0
Reserved – A write to this location has no effect. A read returns 0.
0
MCERRINT
RCU
0
Microcontroller error – This interrupt is generated by a micro
read/write to a reserved location.
