slavelastbyte

Function specification

void slavelastbyte( )

Parameters returned

none.

Prerequisites

Adapter must be configured using setup. This function would normally
only be called following the end of a transmission in slave write mode –
when the adapter is being read as a slave, by another master, not when
writing
to a slave using the adapter.

Functional description

This function is used when the adapter is a slave being read by a master
elsewhere on the bus – the adapter is in slave write mode. The function
must be called immediately after the master indicates the last byte has
been read (by not acknowledging that byte) this function is required to
clear the I

C data lines so that the master can send a stop signal.
