Table 92.
(EMCStaticwaitPage0-3 - 0xFFE0 8210, 230, 250, 270)
The EMCStaticWaitPage0-3 registers enable you to program the delay for asynchronous
page mode sequential accesses. It is recommended that these registers are modified
during system initialization, or when there are no current or outstanding transactions. This
can be ensured by waiting until the EMC is idle, and then entering low-power, or disabled
mode. This register is accessed with one wait state.
Table 5–93
Table 93.
0xFFE0 8214, 234, 254, 274)
The EMCStaticWaitWr0-3 registers enable you to program the delay from the chip select
to the write access. It is recommended that these registers are modified during system
initialization, or when there are no current or outstanding transactions. This can be
ensured by waiting until the EMC is idle, and then entering low-power, or disabled
mode.These registers are not used if the extended wait (EW) bit is enabled in the
EMCStaticConfig register. These registers are accessed with one wait state.

Chapter 5: LPC24XX External Memory Controller (EMC)
Number of wait states for asynchronous page mode read
accesses after the first read:
(n+ 1) CCLK cycle read access time. For asynchronous
page mode read for sequential reads, the wait state time
for page mode accesses after the first read is
(WAITPAGE + 1) x tCCLK.
32 CCLK cycle read access time (POR reset value).
Reserved, user software should not write ones to
reserved bits. The value read from a reserved bit is not
defined.
Non-page mode read or asynchronous page mode read,
first read only:
(n + 1) CCLK cycles for read accesses. For
non-sequential reads, the wait state time is (WAITRD +
1) x tCCLK.
32 CCLK cycles for read accesses (POR reset value).
Reserved, user software should not write ones to
reserved bits. The value read from a reserved bit is not
defined.
