HT98R068-1 Two-way Radio OTP MCU
Read 1Eh Flow
Flow description:
<91E00>: Read the 1Eh register. A data response will be sent to 1Eh after this
command is transmitted.
CLI Command
This interface protocol is different from the I/O command. For the write mode it must
contain three bytes of 20-bit SPI data and two for the read mode. To excute the CLI
command, the first byte is ID code, then the 16-bit address and finally the 16-bit data.
Reading data will have no data byte. The ID code of the read/write mode is different.
IDcode >> Read/Write: 14181/14082, must be correct so that the audio processor will
continue to receive successive data. When the data is written, the audio processor will
reply with 14000 which means that the data is correctly written, otherwise it means no
data written.
