1015 * flash_strobe_adjustment E N, [1 - 0xff]
1016 *
1017 * The formula above is written as below to keep it on one
1018 * line:
1019 *
1020 * l / 10^6 = w / e * a
1021 *
1022 * Let's mark w * a by x:
1023 *
1024 * x = w * a
1025 *
1026 * Thus, we get:
1027 *
1028 * x = l * e / 10^6
1029 *
1030 * The strobe width must be at least as long as requested,
1031 * thus rounding upwards is needed.
1032 *
1033 * x = (l * e + 10^6 - 1) / 10^6
1034 * -----------------------------
1035 *
1036 * Maximum possible accuracy is wanted at all times. Thus keep
1037 * a as small as possible.
1038 *
1039 * Calculate a, assuming maximum w, with rounding upwards:
1040 *
1041 * a = (x + (2^16 - 1) - 1) / (2^16 - 1)
1042 * -------------------------------------
1043 *
1044 * Thus, we also get w, with that a, with rounding upwards:
1045 *
1046 * w = (x + a - 1) / a
1047 * -------------------
1048 *
1049 * To get limits:
1050 *
1051 * x E [1, (2^16 - 1) * (2^8 - 1)]
1052 *
1053 * Substituting maximum x to the original formula (with rounding),
1054 * the maximum l is thus
1055 *
1056 * (2^16 - 1) * (2^8 - 1) * 10^6 = l * e + 10^6 - 1
1057 *
1058 * l = (10^6 * (2^16 - 1) * (2^8 - 1) - 10^6 + 1) / e

1062 * (10^6 * (2^16 - 1) * (2^8 - 1) - 10^6 + 1) / EXTCLK freq.
