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 38). 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 11 describes the request message and the corresponding answer message.
