MCP2502X/5X
8.7
The MCP2502X/5X can be serially programmed while
in the end application circuit. This is simply done with
two lines for clock and data, and three other lines for
power, ground and the programming voltage. This
allows
unprogrammed devices and then program the device
just before shipping the product, also allowing the
most recent firmware (or a custom firmware) to be
programmed.
The device is placed into a program/verify mode by
holding the GP4 and GP5 pins low while raising GP7
(V
programming specification, “MCP250XX In-Circuit
Serial Programming™ (ICSP)”, DS20072, for more
information). GP4 becomes the programming data and
GP5 becomes the programming clock. Both GP4 and
GP5 are Schmitt Trigger inputs in this mode. The signal
definitions are summarized in Table 8-1
