43 * flash programming support for NXP LPC8xx,LPC1xxx,LPC43xx,LP5410x and LPC2xxx devices.
45 * @todo Provide a way to update CCLK after declaring the flash bank. The value which is correct after chip reset will
46 * rarely still work right after the clocks switch to use the PLL (e.g. 4MHz --> 100 MHz).
49 * currently supported devices:
50 * variant 1 (lpc2000_v1):
58 * variant 2 (lpc2000_v2):
67 * - 176x (tested with LPC1768)
69 * lpc4300 (also available as lpc1800 - alias)
70 * - 43x2 | 3 | 5 | 7 (tested with LPC4337/LPC4357)
74 * - 810 | 1 | 2 (tested with LPC810/LPC811/LPC812)
82 * - 11Uxx (tested with LPC11U34)
87 * - 15x7 | 8 | 9 (tested with LPC1549)
90 * - 54101 | 2 (tested with LPC54102)
