Functional Description
The following tasks are performed at each interrupt.
•
XMTSERV
This interrupt was generated due to a FIFO access. Since this is the
last byte of this transfer,
is empty. When read,
indicate a repeated start and set the
fer is a data receive.
• interrupt
MCOMP
This interrupt was generated because all data has been transferred
( = 0). If no errors were generated, a start condition is initi-
DCNT
ated. Clear the

•
RCVSERV
This interrupt is generated due to the arrival of a byte in the receive
FIFO. Simple data handling is all that is required.
• interrupt
MCOMP
The transfer is complete.
