To the person concerned
In the process of using LMK03318 at the customer, Customer wants to confirm unusual case on I2C Slave address.
If you look at the data sheet, the I2C slave address must have one of the values of 0x50, 51,53 according to the Strapping on GPIO.
However, when customer uses the above address to access LMK03318 via I2C, it won't be able to access LMK03318t
But when uses one of 0x54,0x55,0x57 to access the address, Normally, cutomer can access register.
Based on the data sheet, the third bit is 0 unconditionally, but can only be accessed if it is 1.
When read the PRODID Register of the device with the address of one of 0x54,0x55,0x75, the device ID in the datasheet is read normally as below log.
I would like to ask you to check if the value should be 0 or 1 in the third bit.
Boot@ i2c probe
Valid chip addresses: 55 <== Slave address0x51이 되어야 하는데, 0x55로 확인이 됩니다.
Boot@ i2c md 55 0x0 0x10 <== For slave address 0x55 , read registers in the range of offset:0x0 to 0x10
0000: 10 0b 33 02 00 00 00 00 6a 00 02 00 d9 00 00 00 ..3.....j....... <== Sequentially, R0, R1, R2, .... 이며, R2--> 0x33, R3 --> 0x02
Thank you
