A low-active signal used to hard-reset the UFS device. UFS 3.1 vs. eMMC Pinout
UFS 3.1 utilizes a full-duplex serial interface with MIPI M-PHY physical layer and UniPro link layer protocols. This architecture allows simultaneous reading and writing, drastically increasing throughput. The physical manifestation of this advanced architecture is a grid of solder balls (BGA) underneath the chip. UFS 3.1 Physical Package (BGA) ufs 3.1 pinout
Unlike UFS 2.1, UFS 3.1 strictly requires the hardware reset signal to be implemented to properly initialize the device after power-on. A low-active signal used to hard-reset the UFS device
