41 * flash programming support for NXP LPC8xx,LPC1xxx,LPC4xxx,LP5410x and LPC2xxx devices.
43 * @todo Provide a way to update CCLK after declaring the flash bank. The value which is correct after chip reset will
44 * rarely still work right after the clocks switch to use the PLL (e.g. 4MHz --> 100 MHz).
47 * currently supported devices:
48 * variant 1 (lpc2000_v1):
56 * variant 2 (lpc2000_v2):
65 * - 176x (tested with LPC1768)
67 * - 178x (tested with LPC1788)
69 * lpc4000: (lpc1700's alias)
71 * - 408x (tested with LPC4088)
73 * lpc4300: (also available as lpc1800 - alias)
74 * - 43x2 | 3 | 5 | 7 (tested with LPC4337/LPC4357)
78 * - 810 | 1 | 2 (tested with LPC810/LPC811/LPC812)
79 * - 822 | 4 (tested with LPC824)
