DC Electrical Characteristics
Note 4: The HALT mode will stop CKI from oscillating in the RC and crystal configurations by bringing CKI high. HALT test conditions: L, and G0..G5 ports configured
as outputs and set high. The D port set to zero. All inputs tied to V
Note 5: The user must guarantee that D2 pin does not source more than 10 mA during RESET. If D2 sources more than 10 mA during reset, the device will go into
programming mode.
Note 6: Pins G6 and RESET are designed with a high voltage input network. These pins allow input voltages greater than V
to V
(typical). These two pins will not latch up. The voltage at the pins must be limited to less than 14V.
