001 indicates the operation auxiliary parameter
configuration table.
010 means to write the write end RAM, read the
receive end RAM,
100 represents the operating system parameter
table,
101 means to configure the AMBE3000 register
110 means the operation writes the RAM, reads the
RAM,
111 means to configure the AMBE1000 register
The Cmd highest bit selects whether this is a read operation or a write operation, and the lower 3
bits selects the category of this read/write operation.
Addr is the starting address of this read/write. The data that is subsequently written (or read) will
start from the starting address and will be accumulated one by one. It will continue to accumulate
every time CS is valid.
When Cmd[6]=1'b0, Addr represents 8bits (high order first), and the read/write start address
is Addr;
When Cmd[6]=1'b1, Addr indicates 16bits (high order first), and the read/write start address
is {Addr[2:0], Addr[15:8]}.
1. Write 0x01 to register 0x80 of the register system parameter table. The format is:
Cmd Data
8’b 0 0000 100 8’b1000 0000
2, read the end 1.2KRAM from 0x30 2 bytes of data (data content is 0x01, 0x02) format:
Cmd Addr Data0 Data1
8’b 1 0000 010 8’b0011 0000 8’b0000 0001 8’b0000 0010
In addition, the OPMode bit of Cmd is 101, 111 is configured for different types of external vocoder
registers, and 011 is for reading and writing tones or other prompts.

Frame type Address Description
Voice LC Header 0x00~0x0b 0x00~0x08: A total of 72bit is the control letter;
0x09~0x0b: A total of 24 bits is the check
information, and the MCU is optional.
