Reset Register (RESET)
Writing in this register (0 or 1) triggers an asynchronous reset. This register can only be
written.
All registers return to reset state. The chip returns in power-down. So all the following
blocks are reset:
•
All registers to default value
•
Wake-up function.
•
Clock recovery function.
And with the power-down state, reset is applied to the following blocks:
•
Synthesizer dividers.
•
Clock recovery function.
•
PLL lock detect.
•
From powering up the supplies, it takes about 10 µs or at least 1.8V before the reset
state is established (Power-on Reset).
•
From reseting the device, one should wait about 10 µs before re-programming
•
RSSI detection block.
•
Discriminator clock (455 kHz).
