2.4.4.5.7 READ Command
This command aims at reading the value of the register whose address is specified in the request message. This
command is valid in all operating modes. However, in OPM4 and OPM6, the use of the READ command is
restricted (see Table 4-3). If an access outside the allowed address range is performed, the access is discarded
as invalid and an SPI error occurs.
