Note 16: Absolute maximum ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications are not ensured when
operating the device at absolute maximum ratings.
Note 17: Rate of voltage change must be less than 0.5V/ms.
Note 18: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open.
Note 19: The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations. Test conditions: All inputs tied to V_CC, L and G ports TRI-STATE
and tied to ground, all outputs low and tied to ground.
Note 20: 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 (typical). These two pins will not latch up. The voltage at the pins must be limited to less than 14V.
Note 21: To maintain RAM integrity, the voltage must not be dropped or raised instantaneously.
