Functional Description
2.4.4.5.9 WRITEL
This command aims at updating the value of the register whose address is specified in the request message. This
command is valid in all operating modes. However, depending on the active operating mode, this command is
restricted to a given address range or specific registers (see Table 4-4). If an access outside the allowed address
range is performed, the access is discarded as invalid and an SPI error occurs.
At the reception of this command, the least significant byte of the internal buffer is written with the specified value,
the contents of the buffer is copied to the register at the specified address and the complete write buffer is cleared.
Table 2-11 describes the request message and the corresponding answer message.
