7-2-3. Write Buffer Registers (03h – 06h)
There are four write data buffer registers at address: 03h – 06h. To perform a write, the host
can either use a single command or perform separate writes to the following addresses.
The host can write to sensor register map in single byte transfer:
The host can burst write data start from address = 00h with following data byte,
A[15:8]
、
A[7:0]
、
18h
、
data[0].
Or the host can do four serial bus writes and write one data byte into serial bus register with
the following steps.
・
Write A[15:8] to address = 00h of interface configuration registers.
・
Write A[7:0] to address = 01h of interface configuration registers.
・
Write data[0] to address = 03h of interface configuration registers.
・
Write 18h to address = 18h of interface configuration registers.(1byte, new request, write)
[Note] Read Serial Control register(02h). If Req = 0 (02h[3]), controller is finished with write.
7-2-4. Read Buffer Registers (07h – 0Ah)
There are four read data buffer registers at address: 07h – 0Ah. To perform a read, the host
can either use a single streaming command or perform separate commands to the following
addresses. After the read request is done by the internal serial bus bridge controller, the Req
bit is cleared to 0 and read data is stored in rd_buf1 – rd_buf4 (address = 07h – 0Ah).
For single byte read request the host can burst write A[15:8], A[7:0], 1Ch at start address =
00h. The host needs to read the command register until the Req bit is cleared to 0, then read
“read data buffer” for read data at address = 07h.
The host can perform a single byte read by individually programming the following registers.
・
Write A[15:8] to address = 00h of interface configuration registers.
・
Write A[7:0] to address = 01h of interface configuration registers.
・
Write 1Ch to address = 02h of interface configuration registers.(1byte, new request, read)
[Note] Read address = 02h. If Req = 0 (02h[3]), controller is finished with read data[0] from
address = 07h.
