SRAM, ROM or I/O Burst Read with Wait and Hold
Bank Register Bit Settings
Notes:
1. WBE2:3 are address bits 30:31 if the bus width is programmed as byte or halfword.
2. See Table 20 on page 34 for WBE signal denitions based on bus width.
3. WBE signals can be read/write byte enables based on the setting of IOCR[BEM].
4. When in Byte Enable Mode (IOCR[BEM] = 1), the BLast signal appears on the multiplexed OE[XSize1][BLast] out-
put, as described in Table 4 on page 8.
5. Wait must be programmed to a value
(CSon + OEon). If Wait > (CSon + OEon), then all signals will retain the
values shown in cycle 3 until the Wait timer expires.
6. If Hold is programmed > 001, all output signals retain the values shown in cycle 7 until the Hold timer expires.
7. Data parity is only checked when IOCR[RDM] = 11 and BRHx[PCE] is set.
