Function Name:
void
si446x_get_ph_status
(U8 PH_CLR_PEND)
Description:
Gets the Packet Handler status flags. Optionally clears them.
Input Parameter(s):
PH_CLR_PEND Flags to clear.
Return Value:
None
Function Name:
void
si446x_get_modem_status
( U8 MODEM_CLR_PEND )
Description:
Gets the Modem status flags. Optionally clears them.
Input Parameter(s):
MODEM_CLR_PEND : Flags to clear.
Return Value:
None
Function Name:
void
si446x_get_chip_status
( U8 CHIP_CLR_PEND )
Description:
Gets the Chip status flags. Optionally clears them.
Input Parameter(s):
CHIP_CLR_PEND Flags to clear.
Return Value:
None
Function Name:
void
si446x_ircal
(U8 SEARCHING_STEP_SIZE, U8 SEARCHING_RSSI_AVG, U8
RX_CHAIN_SETTING1, U8 RX_CHAIN_SETTING2)
Description:
Performs image rejection calibration. Completion can be monitored by polling CTS
or waiting for CHIP_READY interrupt source.
Input Parameter(s):
SEARCHING_STEP_SIZE
SEARCHING_RSSI_AVG
RX_CHAIN_SETTING1
RX_CHAIN_SETTING2
Return Value:
None
Function Name:
void
si446x_protocol_cfg
(U8 PROTOCOL)
Description:
Sets the chip up for specified protocol.
Input Parameter(s):
PROTOCOL:
0 = Packet format is generic, no dynamic reprogramming of packet handler proper-
ties.
1 = Packet format is IEEE802.15.4g compliant. The following properties are over-
riden: PKT_CRC_CONFIG, CRC_ENDIAN/BIT_ORDER in PKT_CONFG1 for TX
and RX, PKT_FIELD_1_CRC_CONFIG for RX.
Other applicable properties in the packet handler group still need to be pro-
grammed.
Field 1 should have the length of 16 bits to contain the PHR with PKT_LEN_-
FIELD_SOURCE set to 1 for RX.
PSDU field shall use Field 2 with variable length.
Field 2 length should be set to the maximum allowed including the anticipated FCS
length. It is anticipated that the FCS will be calculated by the host and transmitted
over the air. Si4440 will receive PHR and put FCS in the FIFO for the host to retrieve
and check. Therefore, CRC shouldn't be enabled on Si4440.
Return Value:
None
