Note 1 Rate of voltage change must be less than 10 V mS
Note 2 Supply current is measured after running 2000 cycles with a square wave CKI input CKO open inputs at rails and outputs open
Note 3 The HALT mode will stop CKI from oscillating in the RC and crystal configurations HALT test conditions L and G0 G5 ports configured as outputs and set
high The D port set to zero All inputs tied to VCC The comparator and the Brown Out circuits are disabled
Note 4 Pins G6 and RESET are designed with a high voltage input network 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 750X
(typical) These two pins will not latch up The voltage at the pins must be limited to less than 14V
