TEST MODES
As explained in the functional description, The SP5655 can
be programmed into a numb er of test modes. These are invoked
by programming Hex codes into byte 4, those most commonly
used being shown in Table 6.
Other codes will also apply due to don’t care conditions, which
are assumed to be 1 in the Table.
NOTE:
When looking at F
or F
signals from ports P7 and P6. byte
should be sent twice, first to set the desired reference division
ratio then to switch on the chosen test mode.
The pulses can then be measured by simply connecting an
oscilloscope or counter to the relevant output pin on the test board.
