Device MAIN domain supports one standard-based serial interface engine - Universal
Flash Storage (UFS) interface with an integrated M-PHY. UFS provides the following
main features:
- Support of Universal Flash Storage Host (UFS2.1, JESD220C)
- Support of Universal Flash Storage Host Controller Interface (UFSHCI,
JESD223C)
- Support of UFS interconnect - MIPI UniPro (v.1.60, 2013) and MIPI M-PHY
(v3.1, 2014)
- Supports speeds 1.46 Gbps (Gear 1), 2.91 Gbps (Gear 2) and 5.83 Gbps (Gear
3), 2-lanes
- Support of all UFS mandatory SCSI commands required by JEDEC
specification
- Master bus Interface: one 64-bit master interface for data transfers, 48-bit
address width, embedded
- DMA within the host controller with support of little-endian mode only
- Configuration Bus Interface: one 32-bit slave interface for configuration
access, support of linear incrementing addressing mode and only aligned
accesses
- ECC support on internal RAMs
- M-PHY Features: supports reference clocks of 19.2 MHz and 26 MHz
