The buffer status register will relay to the
the status of the message buffer when the data
ready request interrupt occurred. The
MSG_END bit will be set high when the data
(including address codeword and message code-
word) is at the end of this data ready interrupt
call.Thevaliddatalengthofthemessagebuffer
is determined by bit count_0 to count_5. If
MSG_END is low, the data length is more
C
than 46 or data is not at the end, the C should
wait for the next data ready interrupt until the
bit MSG_END is set high. Example 1: if the
data read from 0031H is 95H when a new
data ready interrupt occurred, it means the to-
tal data length is 21 including the address code-
word in this call and the message is terminated
(bit MSG_END =1). The figure below illus-
trates example 1.
