3.5 IAP.1: In-Application Programming API not present on flashless parts
|
||
|
|
Introduction:
|
||
|
|
The LPC43x0 microcontrollers contain an APIfor In-Application Programming of flash
|
||
|
|
memory. This API also allows identification of the part.
|
||
|
|
Problem:
|
||
|
|
On the LPC43x0 microcontrollers, the IAP API is not present. The ISP interface is present
|
||
|
|
which allows the part to be identified externally (via the UART) but part identification is not
|
||
|
|
possible internally using the IAP call because it is not implemented.
|
||
|
|
The first word of the Part ID can be read directly from OTP at 0x40045000. The second word of the Part ID is always
|
||
|
|
'0' on flashless parts. */
