Reset (NRESET)
The SX1501, SX1502 and SX1503 generate their own power on reset signal after a power supply is connected
to the VDDM pin. The reset signal is made available for the user at the pin NRESET. The rising edge of the
NRESET indicates that the startup sequence of the SX1501, SX1502 or SX1503 has finished. NRESET must be
connected to VDDM (or greater) either directly, or via a resistor.

Figure 7 – Power-On / Brown-out Reset Conditions
1. Device behavior is undefined until VDDM rises above VPOR, at which point NRESET is driven to GND
by the SX1501, SX1502 or SX1503.
2.
After tRESET, NRESET is released (high-impedance) by the SX1501, SX1502 or SX1503 to allow it to be
pulled high by an external resistor.
3.
In operation, the SX1501, SX1502 and SX1503 may be reset at anytime by an external device driving
NRESET low during tPULSE. Chip can be accessed normally again after NRESET rising edge.
