Note 2: Rate of voltage change must be less than 0.5V/ms.
Note 3: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open.
Note 4: The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations. Test conditions: All inputs tied to V_CC, L, C and G ports TRI-STATE
and tied to ground, all outputs low and tied to ground.
Note 5: Pins G6 and RESET are designed with a high voltage input network for factory testing. These pins allow input voltages greater than V_CC and the pins will
have sink current to V_CC when biased at voltages greater than V_CC (the pins do not have source current when biased at a voltage below V_CC). The effective
resistance to V_CC is 750Ω (typ). These two pins will not latch up. The voltage at the pins must be limited to less than 14V.
Note 6: To maintain RAM integrity, the voltage must not be dropped or raised instantaneously.
