7.5 Connections for Unused Pins and Modules

Table 7-3 Connections for Unused Pins – RGZ Package

FUNCTION	SIGNAL NAME	PIN NUMBER	ACCEPTABLE PRACTICE⁽¹⁾	PREFERRED PRACTICE⁽¹⁾
GPIO	DIO_n	6–12 14–21 26–32 36–43	NC or GND	NC
32.768-kHz crystal	X32K_Q1	4	NC or GND	NC
32.768-kHz crystal	X32K_Q2	5	NC or GND	NC
DC/DC converter⁽²⁾	DCDC_SW	33	NC	NC
DC/DC converter⁽²⁾	VDDS_DCDC	34	VDDS	VDDS

(1) NC = No connect

(2) When the DC/DC converter is not used, the inductor between DCDC_SW and VDDR can be removed. VDDR and VDDR_RF must still be connected and the 22 uF DCDC capacitor must be kept on the VDDR net.
