CONTINUOUS WRITES TO
VOLATILE MEMORY
Continuous writes are possible only when writing to the
volatile memory registers (address 00h, 01h, and 04h).
Figure 7-3 shows the sequence for three continuous
writes. The writes do not need to be to the same volatile
memory address.
7.5.4
CONTINUOUS WRITES TO
NON-VOLATILE MEMORY
Continuous writes to non-volatile memory are not
allowed, and attempts to do so will result in a command
error (CMDERR) condition.
