Units

tAAR

Address resolution time per IRK. Total time for several IRKs

is given as (1 µs + n * t_AAR), where n is the number of IRKs.

(Given priority to the actual destination RAM block).

µs

tAAR,8

Time for address resolution of 8 IRKs. (Given priority to the

actual destination RAM block).

µs

6.3 BPROT — Block protection

The mechanism for protecting non-volatile memory can be used to prevent erroneous application code

from erasing or writing to protected blocks.
