ADuC841/ADuC842/ADuC843
I
The ADuC841/ADuC842/ADuC843 support a fully licensed
I
hardware slave and software master. SDATA is the data I/O pin,
and SCLOCK is the serial clock. These two pins are shared with
the MOSI and SCLOCK pins of the on-chip SPI interface. To
enable the I
(see SPE in Table 18) or the SPI interface must be moved to
P3.3, P3.4, and P3.5 via the CFG841.1/CFG842.1 bit. Application
Note uC001 describes the operation of this interface as imple-
mented and is available from the MicroConverter website at
www.analog.com/microconverter.
