Synchronous Serial Ports (SSP)
17.1 Overview
The Synchronous Serial Port is a host controller which provides a flexible interface for
inter-IC and removable media control and communication. The SSP supports MMC/SD/SDIO
1-bit, 4-bit, and 8-bit modes; SPI master and slave modes; and Texas Instruments SSI mode.
The SSP is fully compliant with the eMMC 4.4 standard. Specifically, it supports Power-on
and alternate boot mode and is designed to perform both SDR and DDR operations at the
maxinum speed of 52 MHz. In SPI mode, the SSP has enhancements to support 1-bit legacy
MMC cards, and SPI master dual (2-bit) and quad (4-bit) read modes are also supported.
The SSP has a dedicated DMA channel in the bridge and can also be controlled directly by
the CPU through PIO
registers.Figure 17-1
illustrates one of the four SSP ports included
on the i.MX28. Each SSP is independent of the other and can have separate SSPCLK
frequencies.
