(1) All voltages are with respect to VSS.
(2) Maximum current drain per pin is for one pin at a time, limited by an external resistor.
Note: This device contains circuitry designed to protect against damage due to high electrostatic voltages or electric fields. However, it is recommended that normal precautions be taken to avoid the application of any voltages higher than those given in the maximum ratings table to this high impedance circuit. For maximum reliability all unused inputs should be tied to either VSS or VDD.




Description

The MC68HC05L28 has two modes of operation available to the user single chip and RAM bootloader. The MC68HC705L28 also has two modes of operation single chip and EPROM/RAM bootloader. Table 2-1 and Table 2-2 show the conditions required to enter each mode on the rising edge of RESET.
