36 * flash programming support for NXP LPC17xx and LPC2xxx devices.
38 * @todo Provide a way to update CCLK after declaring the flash bank. The value which is correct after chip reset will
39 * rarely still work right after the clocks switch to use the PLL (e.g. 4MHz --> 100 MHz).
42 * currently supported devices:
43 * variant 1 (lpc2000_v1):
51 * variant 2 (lpc2000_v2):
60 * - 176x (tested with LPC1768)
62 * lpc4300 (also available as lpc1800 - alias)
63 * - 43x2 | 3 | 5 | 7 (tested with LPC4337/LPC4357)
