a. VDD_RF collectively refers to the VDDIF, VDDLNA, VDDPX, and VDDRF RF power supplies.
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 with VDDO shown as their power domain):
GPIO[3], GPIO[5], GPIO[6]
SCL, SDA
N_MODE
SPIM_CS_N, SPIM_CLK
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 Cypress compatibility guide for configuration details.
