Reset (NRESET)
The SX1504, SX1505 and SX1506 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 SX1504, SX1505 or SX1506 has finished. NRESET must be
connected to VDDM (or greater) either directly, or via a resistor.

1. Device behavior is undefined until VDDM rises above VPOR, at which point NRESET is driven to GND
by the SX1504, SX1505 or SX1506.
2.
After tRESET, NRESET is released (high-impedance) by the SX1504, SX1505 or SX1506 to allow it to be
pulled high by an external resistor.
