Notes:
DD
1. For pins SCLK, SDI, SEN, XEN, and PDN.
2. For pins CKN, CKP, ION, and IOP.
3. For XIN pins (Si4133T pin 7 and Si4201 pin 7).
4. The XSEL bit controls an internal divide-by-two circuit on the Si4201 and does not affect the XOUT pin. The DIV2 bit
= 2.7 to 3.0 V, T
controls an internal divide-by-two circuit on the Si4133T.
