ST25DVxxx specific features

219

Other dynamic registers are dedicated to process monitoring:

•

I2C_SSO_Dyn is dedicated to data memory protection

•

MB_LEN_Dyn, MB_CTRL_Dyn are dedicated to fast transfer mode

•

IT_STS_Dyn is dedicated to interrupt

In I2C, read and write of the Dynamic registers is done using usual I2C read & write

command at dedicated address. (E2 =0 in device select).

In RF read or write accesses to the Dynamic registers are associated to the dedicated

commands, Read Dynamic Configuration, Write Dynamic Configuration and Read Message

Length.
