Low Power, Low Profile ±2 g Dual Axis Accelerometer with I2C Interface

Unspecified 

Fourth cycle: Master device sends a START command

followed by calling Memsic device address with a WRITE

(8th SCL, SDA keep low). An “acknowledge” should be

sent by Memsic device at the end.

Fifth cycle: Master device writes to Memsic device a

“[00000000]” as the starting address for which internal

memory is to be read. Since “[00000000]” is the address of

internal control register, reading from this address can serve

as a verification of operation and to confirm the write

command has been successful. Note: the starting address in

principle can be any of the 5 addresses. For example, user

can start read from address [0000001], which is X channel

MSB.

Sixth cycle: Master device calls Memsic device address

with a READ (8th SCL cycle SDA line high). Memsic

device should acknowledge at the end.

Seventh cycle: Master device cycles SCL line, first

addressed memory data appears on SDA line. If in step 7,

“[00000000]” was sent, internal control register data

should appear (in the following steps, this case is assumed).

Master device should send acknowledge at the end.

Eighth cycle: Master device continues cycle SCL line, next

byte of internal memory should appear on SDA line (MSB

of X channel). The internal memory address pointer

automatically moves to the next byte. Master

acknowledges.

Ninth cycle: LSB of X channel. In the case that TOEN bit

of internal register was set to “1”, the MSB and LSB of

TOUT (temperature) should appear in last two steps.

Tenth cycle: MSB of Y channel.

Eleventh cycle: LSB of Y channel.

Master ends communications by sending NO acknowledge

and followed by a STOP command. Note: if mater device

continues to cycle SCL line, the memory pointer will go to

sixth and seventh positions, which always have

“[00000000]”. After seventh position, pointer will go to

zero again.

Optional: Master powers down Memsic device by writing

into internal control register. (See step 1 through 4 for

WRITE operation)
