enabled, then click OK. The EV kit software checks
the serial-port status lines to confirm that the cor-
rect port has been selected. When the program
detects the 68HC16 module, the code contained in
KIT1276.C16 is automatically downloaded to

The Device Output section displays the test device out-
put code in hex and decimal format. The displayed volt-
age reading is calculated from the device output code
and the reference voltage in the Device Parameters
section. There are also options to take single readings or
to automatically display a new reading every 200ms. The
clock rate used for these readings is determined by the
setting in the Clock Divider window found in the SPI
Parameters section. The Collect Samples button opens
a dialog box to collect and graph output readings or to
record readings to a disk file.
The SPI Parameters section sets the timing parame-
ters used by the 68HC16’s serial peripheral interface
(SPI). The SPBR register, that controls the SPI clock fre-
quency, has a range of 2 to 255 and yields clock fre-
quencies between 33kHz and 4.19MHz. The DTL regis-
ter, which controls the delay between conversion
cycles, has a range of 0 to 255 for delays between 1µs
and 487µs. Timing values are displayed along with the
total conversion time and sample rate. To observe
