A.5
USB COMMUNICATIONS PROTOCOL
The USB protocol used by the PICkit 1 Flash Starter Kit is a very simple
command/response type protocol. Multiple commands can be put together to fill the 8
bytes of a USB packet. If a command cannot fill the 8 bytes and it is not desired to use
a second command to fill the packet, the packet should be padded with ‘Z’ to indicate
no operation.
A.5.1
Commands
? ‘C’ <word> – Configuration Memory Write mode. Word parameter ignored. Use
‘W’ to write to configuration memory.
? ‘c’ – Download Command Table. 15 bytes to follow (two 8 byte packets) containing
the 6-bit commands in the following order:
- Load Configuration memory
- Load data for Program memory
- Load data for EE Data memory
- Read data from Program memory
- Increment Address
- Begin programming (internally timed)
- Begin programming (externally timed)
- End programming (externally timed)
- Bulk Erase Program memory
- Bulk Erase EE Data memory
The last 4 commands are undefined but the second data packet will be filled out.

‘D’ <byte> – Write EE Data memory. Data is passed as the byte.
‘E’ – Bulk Erase Program memory
‘e’ – Bulk Erase Data memory
‘g’ – Get n bytes from device (n is a word)
‘I’ <word> – Increment Address N times. N is passed as word.
‘P’ – Enter Programming mode. Turns V PP and V DD on.
‘p’ – Exit Programming mode. Turns V DD and V PP off.
‘R’ – Read Program memory. ‘R’ always returns 4 words. If the end of PGM
memory is reached, it pads with 0’s. It is the responsibility of the host software to
determine if padding occurred by keeping track of the program counter.
‘r ’ – Read EE Data memory. ‘r ’ always returns 8 bytes. If the end of Data memory
is reached, it pads with 0’s. It is the responsibility of the host software to determine
if padding occurred by keeping track of the program counter.
‘S’ <program memory length, data memory length> – Calculates Program
Memory Checksum and Data Memory Checksum. The checksum is calculated on
the first N p words of the program memory and the first N d bytes of the data
memory. N p and N d are both words passed as the length parameter. The return
value is 3 bytes in length: the first word is the Program Memory Checksum, and
the last byte is the Data Memory Checksum.
‘t’ – Transmit n bytes to device (n is a word)
‘V’ <byte> – Power and special feature control. The byte following command is
used to control. V DD power to the target and to enable/disable a 2.5 kHz 50%
square wave.
‘v’ – Return version information. The following bytes are returned:
<Major><Minor><Dot>.
‘W’ <word> – Write Program Memory. Loads the write latch, sends the write
command and increments to the next address.
