I have some questions, if you look thru this,
0000 L0000 = 0x0000
0000 L0010 = 0x0010 Why do the numbers "jump", here??
0010 L0011 = 0x0011
0011 L0012 = 0x0012
0012 L0013 = 0x0013
0013 L0014 = 0x0014
0014 L0015 = 0x0015
0015 L0016 = 0x0016
0016 L0017 = 0x0017
snip
0030 L0031 = 0x0031
0031 L0033 = 0x0033
0033 L0034 = 0x0034
0034 L0035 = 0x0035
0035 L0036 = 0x0036
0036 L0037 = 0x0037
0037 L0038 = 0x0038
0038 L0039 = 0x0039 What happens here?.
0039 L0048 = 0x0048
0048 L0058 = 0x0058
0058 L0059 = 0x0059
0059 L005A = 0x005A
005A L005B = 0x005B
005B L005D = 0x005D
snip
5006 L5009 = 0x5009 Why the jump to the 5 "prefix"
5009 L500C = 0x500C
500C L500F = 0x500F
500F L5012 = 0x5012
5012 L6000 = 0x6000
