SRAM Read Extended with Ready (Asynchronous Ready Mode)
Bank Register Settings
Notes:
1. WBE2:3 are address bits A30:31 if the bus width is programmed as byte or halfword.
2. Not Byte Enable Mode (IOCR[BEM] = 0). WBE0:3/BE0:3 are write byte enables and OE/BLAST is OE.
3. Byte Enable Mode (IOCR[BEM] = 1). WBE0:3/BE0:3 are byte enables and OE/BLAST is BLAST
4. Arrows indicate when READY is sampled.
5. IOCR[ARE] is set.
