Specifications

On the Si100x, zero indicates “untimed sleep.” Positive numbers indicate how long to sleep in 1.0s
“ticks” (regardless of mode), and negative numbers indicate the following fractions of a second:
Ticks Sleep time
-1 16ms
-2 31ms
-3 63ms
-4 125ms
-5 250ms
-6 500ms
-7 1000ms
Maximum allowed sleep: 32767 seconds, or 9:06:07.
Encryption
The Si100x supports Basic encryption. AES-128 encryption is not available in the Si100x firmware.
(It is available for RF300/RF301 firmware.)
Alternate Radio Trim settings:
NV Parameter 63 is used on the Si100x. The default value is 183 but you can override this by saving a
new value in NV #63. For the definition of the trim value, refer to the Silicon Labs datasheets.
Vendor-specific settings:
NV Parameter 64 is used on the Si100x.
Bit 0x0001 – Indicates how the TX and RX registers are set in the hardware.
When this bit is clear (set to 0), register 0x0C is set to 0x15, the receive state, and register 0x0D is set
to 0x12, the transmit state. This is the appropriate setting for the RF30x SNAP Engine and any
hardware similarly connected.
When this bit is set (to 1), register 0x0C is set to 0x12 and register 0x0D is set to 0x15. This is the
appropriate setting for the Silicon Labs EZRadio Pro 1000-TCB1 development board and any
hardware similarly connected.
If this bit is incorrectly set radio signal strength will be diminished, as will the radio’s ability to clearly
receive signals. Users developing their own hardware according to the Silicon Labs demonstration
board should be sure to set this feature bit.
Resetting factory parameters does not modify this parameter.
