Tie to ground for external regulator mode (1.7-V to 1.95-V operation). VSS 3, 7, 17, 20, 29 Power Ground X32K_Q1 5 Analog I/O 32-kHz crystal oscillator pin 1 X32K_Q2 6 Analog I/O 32-kHz crystal oscillator pin 2 X24M_N 30 Analog I/O 24-MHz crystal oscillator pin 1 X24M_P 31 Analog I/O 24-MHz crystal oscillator pin 2 EGP Power Ground – Exposed Ground Pad (1) See technical reference manual (listed in Section 11.3) for more details. (2) Do not supply external circuitry from this pin. (3) For design consideration regarding noise immunity for this pin, see the JTAG Interface chapter in the CC13x0, CC26x0 SimpleLink™ Wireless MCU Technical Reference Manual (4) If internal DC/DC is not used, this pin is supplied internally from the main LDO. (5) If internal DC/DC is not used, this pin must be connected to VDDR for supply from the main LDO.
