The C6211/C6211B SBSRAM interface takes advantage of the internal burst counter in the SBSRAM. Accesses default to incrementing 4-word
bursts, but random bursts and decrementing bursts are done by interrupting bursts in progress. All burst types can sustain continuous data flow.

The C6211/C6211B SBSRAM interface takes advantage of the internal burst counter in the SBSRAM. Accesses default to incrementing 4-word
bursts, but random bursts and decrementing bursts are done by interrupting bursts in progress. All burst types can sustain continuous data flow.
ARE/SDCAS/SSADS, AOE/SDRAS/SSOE, and AWE/SDWE/SSWE operate as SSADS, SSOE, and SSWE, respectively, during SBSRAM
accesses.
