I2CMS: I2C Master/Slave Strap;
HIGH (Internal PU) - I2C Slave.
LOW (External PD) - I2C Master.
REF: Clock Reference Strap;
HIGH (Internal PU) - DCLK.
LOW (External PD) - CLKIN/XTALI.
Place 0.1 uF close to pins 6, 16, 23, 29, 12.
STRAPS
External I2C controller for tuning:
* Unmount RW7 and RW8.
* If a weak pull-up on I2C is needed, mount RW4 and RW5.
* I2C controller connections:
- I2C SCL to TP9.
- I2C SDA to TP8.
