oNotes:
.cThe number of memory program lines is
approximate as different commands require
Udifferent amounts of memory.
t4The data memory can be used for storing data
values or LCD messages. On the entry level
ePICAXE-08/18 this memory is shared with the
downloaded program and so a longer program
edecreases the available data memory.
hThe PICAXE-28 has separate ADC pins, with the
Sother types the ADC are combined on the input
pins. L denotes a low-resolution ADC function.
taThe PICAXE-28 and PICAXE-18 microcontrollers
arequire a 4k7 pull up resistor on the reset pin.
