Data Sheet
Figure 43: 3-Wire Serial Data Interface
The AMIS-53000 employs two different data interfaces. Transmit and receive data is exchanged with an external controller through
either a 3-wire or a 4-wire SPI like interface. Selecting the interface, 3-wire or 4-wire is done by writing to bit 7 of the general options B
register.
SPI serial data interface
3-wire serial data interface
AMIS-53000 can be the slave or master
Setup registers descriptions:
Chip Address- Allows a unique value to be transmitted and received with the data packet to identify a unique radio.
Fixed Data Rates- Select the options for one of several fixed data rates.
General Options A- Configure the interface options.
General Options B- Configure the interface options.
Start of Frame- Set a code value that indicates the start of a data packet.
Preamble Length- Select a type of preamble and set the length in bits. (see Section 6.6.3)
Custom Data Rates- Configure parameters for data rates that are not one of the fixed data rates.
CRC Polynomial- Value of the CRC polynomial.
Default Length of Packet- Set a default length for packets.
Broad Cast ID- A general chip ID allowing for transmissions to be received by all radios.
