Host Interface Eight (HI8), Rev. 4
Freescale Semiconductor
16-11
16.8.1.3 Host Dual Data Strobe (HDDS)—Bit 7
When the Host Dual Data Strobe (HDDS) bit is set, the HI8 operates in the Dual Data Strobe Bus
mode; a host bus with separated read and write data strobes. When the HDDS bit is cleared, the
HI8 operates in the Single Strobe Bus mode, i.e. a Host bus with a single Data Strobe signal.
Please see Figure 16-5 for a description of the two types of buses. The HDDS bit is cleared on
hardware reset.

In Single Strobe Bus mode, a DS (Data-Strobe) signal qualifies the access, while a R/W
(Read-Write) signal specifies the direction of it.

In Dual Strobe Bus mode, there are special RD and WR signals that both qualify the
access as being a read or a write access, respectively.
