42 * flash programming support for NXP LPC8xx,LPC1xxx and LPC2xxx devices.
44 * @todo Provide a way to update CCLK after declaring the flash bank. The value which is correct after chip reset will
45 * rarely still work right after the clocks switch to use the PLL (e.g. 4MHz --> 100 MHz).
48 * currently supported devices:
49 * variant 1 (lpc2000_v1):
57 * variant 2 (lpc2000_v2):
66 * - 176x (tested with LPC1768)
68 * lpc4300 (also available as lpc1800 - alias)
69 * - 43x2 | 3 | 5 | 7 (tested with LPC4337/LPC4357)
73 * - 810 | 1 | 2 (tested with LPC810/LPC811/LPC812)
81 * - 11Uxx (tested with LPC11U34)
86 * - 15x7 | 8 | 9 (tested with LPC1549)
88 * The auto variant auto-detects parts from the following series:
101 /* Part IDs for autodetection */
102 /* A script which can automatically extract part ids from user manuals is available here:
