91 Basic firmware description. This will remain with
92 the driver for documentation purposes.
93
94 This represents an I2C firmware file encoded as a
95 string of unsigned char. Format is as follows:
96
97 char[0 ]=len0_MSB -> len = len_MSB * 256 + len_LSB
98 char[1 ]=len0_LSB -> length of first write transaction
99 char[2 ]=data0 -> first byte to be sent
100 char[3 ]=data1
101 char[4 ]=data2
102 char[ ]=...
103 char[M ]=dataN -> last byte to be sent
104 char[M+1]=len1_MSB -> len = len_MSB * 256 + len_LSB
105 char[M+2]=len1_LSB -> length of second write transaction
106 char[M+3]=data0
107 char[M+4]=data1
108 ...
109 etc.
110
111 The [len] value should be interpreted as follows:
112
113 len= len_MSB _ len_LSB
114 len=1111_1111_1111_1111 : End of I2C_SEQUENCE
115 len=0000_0000_0000_0000 : Reset command: Do hardware reset
116 len=0NNN_NNNN_NNNN_NNNN : Normal transaction: number of bytes = {1:32767)
117 len=1WWW_WWWW_WWWW_WWWW : Wait command: wait for {1:32767} ms
118
119 For the RESET and WAIT commands, the two following bytes will contain
120 immediately the length of the following transaction.
