Notes
Power On Reset The minimum VDD rise time for the processor is 0.050V/ms. In the
event that VDD ramps up at a slower rate a delay circuit has been
provided based on the Microchip application note that consists of a
diode, capacitor, and 2 resistors. Due to limitations in space and
component size this protection may prove to be inadequate in some
applications. For this reason the MCLR pin of the processor is made
available as an input to the module so that the OEM may control the
power-on reset.
