with the A2 pin set to 0.
18.45.3 Defined values
<BusId>
0 : SPI bus.
1 : I2C Soft bus.
2 : Parallel bus.
<Size>
Size of data buffer, in bytes. (max. 256 bytes)
<Address>
z For SPI bus :
Not Used
z For Parallel bus :
0 : set the A2 pin to 0 (default)
1 : set the A2 pin to 1
z For I2C Soft bus :
Slave address byte, in hexadecimal format (default “00”).
This is a 7-bits address, shifted to left from 1 bit, padded with the LSB set to 0 (to write), and sent
first on the I2C bus before performing the writing operation.
<Data Buffer> : Data buffer to write on the specific bus.
This parameter must only contain hexadecimal characters (0-9, A-F) Its length must be twice the <Size>
parameter.
