9.10 Program Verification/Code

Protection

If the code protection bit has not been programmed, the

on-chip program memory can be read out for

verification purposes.

The first 64 locations and the last location (Reset

vector) can be read, regardless of the code protection

bit setting.

9.11 ID Locations

Four memory locations 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.

Use only the lower four bits of the ID locations and

always program the upper eight bits as ‘0’s.

9.12 In-Circuit Serial Programming™

The PIC10F200/202/204/206 microcontrollers 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 devices are placed into a Program/Verify mode by

holding the GP1 and GP0 pins low while raising the

MCLR (VPP) pin from VIL to VIHH (see programming

specification). GP1 becomes the programming clock

and GP0 becomes the programming data. Both GP1

and GP0 are Schmitt Trigger inputs in this mode.

After Reset, a 6-bit command is then supplied to the

device. Depending on the command, 16 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

PIC10F200/202/204/206 Programming Specifications.

A typical In-Circuit Serial Programming connection is

shown in Figure 9-10.
