• Manufacturer: California Eastern Laboratories

SYNCWD (SYNCWORD REGISTER, 0x2212)
Sets two bytes of data to be used as the Start-of-Frame Delimiter (SFD). IEEE802.15.4 standard uses 2
symbols as an SFD. The 2 symbols are ‘0xA7’. The ‘7’ is the first of the 2 symbols transmitted.
TDCNF0 (OPERATION DELAY CONTROL 0 REGISTER, 0x2213)
This register sets the delay to power down RF after TX.
TDCNF1 (OPERATION DELAY CONTROL 1 REGISTER, 0x2217)
This register sets the delay for switching between TX and RX.
TXFRM1 (TX FRAME FORMAT1 REGISTER, 0x2215)
This register is used to set the frame format of the TX packet.
AGCCNF3 (AGC CONFIGURATION3 REGISTER, 0x2223)
This register sets AGC operation environment
CCA0 (CCA CONTROL CONFIGURATION0 REGISTER, 0x2248)
This register is used to set CCA operation environment.

RX Preamble Length. Sets the preamble length of the received packet.
The ZIC2410 supports a preamble of 8 symbol length defined in the
IEEE 802.15.4 std. At the same time, the ZIC2410 provides a
configurable preamble length. When ‘n’ value is set in RXPRMLNG
field, the length of the preamble is set to (n+6)symbol. The length of
preamble can be varied from 6 to 21 symbols.
Note: The value of this field should be set the same as the
TXPRMLNG field. It is recommended to use a default value of ‘2’.
Sets the delay time between a packet transmission and RF TX-path
power-down. The delay time is set in 16µs increments. The minimum
and maximum values are 0µs and 240µs respectively.
Reserved
Sets the delay time of the transition from TX to RX state. The delay time
is set in16µs increments. The minimum and maximum values are 0µs
and 240µs respectively.

Reserved
RX Energy Accumulator Window size. AGC calculates the average of
the received signal energy for a defined time when measuring RSSI.
RXEAWS field is used to set the defined time.
