DATA SHEET REV 1.0
7.13 DIAGNOSTICS
The following four tables contain the diagnostic test configurations. To run the diagnostics, load the GC4016 with the
configuration, set address 0 to 00 in order to clear the resets, set address 5 to 00 to release the counter, wait for the checksum
to stabilize (approximately 2²⁰ clock cycles) and then read the checksum, which should match the expected value.
