A2 SAR_DETECT
Can be enabled to perform SAR
detect function (input for external
proximity detection interrupt).
GPIO with wake capability (wake
capability not enabled by default) GPIO[36] In/Out PMU BIDIR_WAKE N/A In, HiZ
A3 TDI JTAG
A4 TDO JTAG
A5 WAKE_UART0_CTS_N
UART0_CTS_N input
Active low (wake-up function) GPIO[37] In/Out PMU BIDIR_WAKE N/A In, HiZ

A9 VCC_SCI0 External SIM supply connection
A10 SCI_EXT_DATA
External SIM data. A 4.7 kΩ pull-up
resistor to VCC_SCI0 is mandatory. GPIO[20] In/Out VCC_SCI0 BIDIR 2 In, PU
A11 VCC_SCI1 SIM supply
A12 SCI_INT_CLK Internal SIM clock GPIO[24] Out VCC_SCI1 BIDIR 2 Out, PD

A19 WAKE_GPIO_0
Wake source (wake capability not
enabled by default) GPIO[28] In/Out PMU BIDIR_WAKE N/A In, HiZ
B2 RING0
Output signal that indicates URC or
data event on UART AT channel. It is
recommended to pull-up this pin with
the application host processor supply
as it will become high impedance
when module is in deep sleep mode.
RING0 is active low (from high to low).
Can be configured with AT+SQNRICFG GPIO[35] In/Out PMU BIDIR_WAKE N/A In, HiZ
