Code Protection
If
the
code
protection
bit(s)
have
not
been
programmed, the on-chip program memory can be
read out for verification purposes.
9.10
ID Locations
Four memory locations (2000h-2003h) are designated
as ID locations where the user can store checksum or
other code identification numbers. These locations are
not accessible during normal execution, but are
readable and writable during program/verify. Only the
Least Significant 4 bits of the ID locations are used.
9.11
In-Circuit Serial Programming
The
PIC16C432
microcontroller
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 customers to manufacture boards
with unprogrammed devices, and then program the
microcontroller just before shipping the product. This
also allows the most recent firmware or a custom
firmware to be programmed.
The device is placed into a Program/Verify mode by
holding the RB6 and RB7 pins low, while raising the
MCLR (VPP) pin from VIL to VIHH (see programming
specification). RB6 becomes the programming clock
and RB7 becomes the programming data. Both RB6
and RB7 are Schmitt Trigger inputs in this mode.
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.
Depending on the command, 14-bits of program data
are then supplied to or from the device, depending if
the command was a load or a read. For complete
details of serial programming, please refer to the
PIC16C6X/7X/9XX Programming Specifications (Liter-
ature #DS30228).
A typical in-circuit serial programming connection is
shown in Figure 9-19.

Note 1: XT, HS or LP Oscillator mode assumed.
2: TOST = 1024TOSC (drawing not to scale). This delay does not occur for RC Osc mode.
3: GIE = ’1’ assumed. In this case after wake-up, the processor jumps to the interrupt routine. If GIE = ’0’, execution will continue in-line.
4: CLKOUT is not available in these osc modes, but shown here for timing reference.
Note:
Microchip does not recommend code
protecting windowed devices.
