Non-volatile memory registers
The device includes several internal registers which are used for customization and
identification.
The initial signature allows read access to all areas but only write access to customer
registers. Write accesses to reserved areas are ignored. Since these registers are
implemented as non-volatile memory cells, writing to the registers needs a specific time
t
prog
after each write access to complete.
As there is no check for the programming time, the user must make sure no other
accesses to the non-volatile memory are made during the programming cycle.
The non-volatile memory must not be addressed during the time t
prog
.
Note
: Before data can be stored in the non-volatile memory, the internal charge pump has
to be switched on for the programming duration by setting register CTRL1, bit 11
CP_CLOCK_EN and register TESTCTRL0, bit 11 WRITE_EN. Register addresses
8h to Fh have to be read out and consulted to calculate the checksum.
