VDDO b

b. If VDDO is not applied, voltage should never be applied to any digital I/O pins (I/O pins should never be driven

or pulled high). The list of digital I/O pins includes the following (these pins are listed in Section 7: “Pin-out and

Signal Descriptions,” on page 40 with VDDO shown as their power domain):

GPIO[3], GPIO[5], GPIO[6]

SCL, SDA

c. VDDTF for Class 2 must be connected to VREG (main LDO output). VDDTF for Class 1 must be connected to

VREGHV (HV LDO output) or an external voltage source. Refer to the Broadcom compatibility guide for

configuration details.
