Entering In-Circuit Serial Programming Mode
The device is placed into a program/verify mode by holding the RB6 and RB7 pins low while rais-
ing the MCLR (V
) pin from V
to V
(see programming specification) and having V
at the

programming voltage. RB6 becomes the programming clock and RB7 becomes the program-
ming data. Both RB6 and RB7 are Schmitt Trigger inputs in this mode, and when RB7 is driving
data it is a CMOS output driver.
After reset, to place the device into programming/verify mode, the program counter (PC) is at
location 00h. A 6-bit command is then supplied to the device. Some commands then specify that
14-bits of program data are then supplied to or read from the device, depending on if the com-
mand was a load or a read. For complete details of serial programming, please refer to the device
specific Programming Specifications.
During the In-Circuit Serial Programming Mode, the WDT circuitry is disabled from generating a
device reset.
