Note 8: Rate of voltage change must be less than 0.5V/ms.
Note 9: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open.
Note 10: The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations. Test conditions: All inputs tied to VCC, L and G0 — G5 configured
as outputs and set high. The D port set to zero.
Note 11: Except pin G7: +100 mA, −25 mA (COP820C only). Sampled and not 100% tested. Pins G6 and RESET are designed with a high voltage input network
for factory testing. These pins allow input voltages greater than VCC and the pins will have sink current to VCC when biased at voltages greater than VCC (the pins
do not have source current when biased at a voltage below VCC). The effective resistance to VCC is 750Ω (typical). These two pins will not latch up. The voltage at
the pins must be limited to less than 14V.
