RW SCRATCHPTR

Pointer to a scratch data area used for temporary storage

during key-stream generation, MIC generation and

encryption/decryption.

The scratch area is used for temporary storage of data

during key-stream generation and encryption.

When MODE.LENGTH = Default, a space of 43 bytes

is required for this temporary storage. MODE.LENGTH

= Extended (16 + MAXPACKETSIZE) bytes of storage is

required.

6.4.9.11 MAXPACKETSIZE

Address offset: 0x518

Length of key-stream generated when MODE.LENGTH = Extended.

RW MAXPACKETSIZE

[0x001B..0x00FB]

Length of key-stream generated when MODE.LENGTH

= Extended. This value must be greater or equal to the

subsequent packet payload to be encrypted/decrypted.

6.4.9.12 RATEOVERRIDE

Address offset: 0x51C

Data rate override setting.

Override value to be used instead of the setting of MODE.DATARATE. This override value applies when the

RATEOVERRIDE task is triggered.
