In the Bus Service API, adl_busread( ), One of the parameter is *
pAcessmode which is a structure, it consists of Opcode and Address
I want to know, what for is it used.
In SPI bus, it is specifed as
For 2403A, One byte can be sent through Opcode parameter.
Two byte can be sent through Address Parameter.
For 2406B, upto 32 bits can be sent through Opcode and address parameter.
For 2400A, in older they have not specified, but in higher version, it is specified as same as 2406B.
What do this mean? ? Please suggest me .
