and `TXD` (J1.7). The firmware operates at 115.2 kbaud, 8 bits, no parity. ISP
will autobaud, and was tested at that same configuration.
* Ground `ISP` and reset board to enter ISP mode.
See the SPLear data sheet, user's guide, and the blog for more documentation,
tutorials, and examples.
### LPCXpresso LPC800 Demo Board
Connect a 3.3V logic level serial port to the demo board, either using
the FTDI footprint at J7 or by accessing pins marked `GNDX` (J6-1),
`PIO0_0-ISP_RX` (J6-10), and `PIO0_4-ISP_TX` (J6-9). Do be very
mindful about the warning to not use a 5V FTDI cable with J7 as that

#### ISP with FlashMagic
The SPLear firmware can be reprogrammed through the built-in bootloader's ISP protocol.
To do this you need a 3.3V logic level serial connection to pins `RXD` and `TXD` referenced
to `GND` and supply between 3.3V and 5V at the `VCC` pin. An FTDI or similar USB serial
cable with 3.3V logic level outputs will work fine.
You also need to be able to push the reset button while grounding the `ISP` pin.
The [FlashMagic][fm] tool is the ISP flash utility that NXP recommends. It is a commercial
product that is free for non-production use.
[fm]: http://www.flashmagictool.com/
With FlashMagic open, make the following settings in its UI:
Select: LPC812M101FDH16
Flash Bank: (blank)
COM Port: (pick your serial port)
Baud Rate: 9600 (faster should work)
Interface: None (ISP)
Oscillator (MHz): 24
Check at least one of the Erase options.
Select your HEX file. The Release build is in `...\LPCWorkspace\PDMSPL\Release\PDMSPL.hex`
in this workspace as configured. You only have to do this once per session, it will re-read
the file each time you program a chip so you can compile, flash, and test.
If you have been using a terminal interactively, exit or have it close the serial port.
Click the big START button to program.
