• WPER Programming

WPER can be set from 10 ms to 328 sec with an accuracy of ±20%. A 10 ms period

clock is used for this period generation.

Bit 8 and 7 give a period multiplication factor of 1, 16 or 256 (with two serial by 16 clock

prescalers).

Bit 6 to 0 give the number of cycles of the divided clock from 1 to 128 (counter).

DATL 5 Data length

Valid in fixed data length mode (STOP = 0).

(00000)

: 1 bit (min data length value)

WPER 9 Wake-up period

Variable from 10 ms to 328 sec with an accuracy of ±20%.(on-chip RC oscillator)

reset value: 960 ms

reset value: (5f)

WL1 7 Minimum delay before TEST1 (check of RSSI level)

Variable from 1ms to 1.024 sec

Delay calculation starts when the reference oscillator starts

reset value: (04)

WL2 3 Minimum delay between TEST 1 and TEST 2 (check of header detection)

Variable as multiple of WL1 from 0 to 31 x WL1

reset value: 2 x WL1

reset value: (2)

ISTU 1 Inhibit stuff mechanism

0: stuff is used for wake-up message

1: no stuff used in the wake-up message

reset value: 0
