User manual
10.21 Static Memory Configuration registers (EMCStaticConfig0-3 -
Table 88.
0xFFE0 8200, 220, 240, 260)
The EMCStaticConfig0-3 registers configure the static memory configuration. 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 accessed with
one wait state.
Table 5–89
synchronous burst mode memory devices are not supported.

8 bit (POR reset value).
16 bit.
32 bit.
Reserved.
Reserved, user software should not write ones to
reserved bits. The value read from a reserved bit is not
defined.
In page mode the EMC can burst up to four external
accesses. Therefore devices with asynchronous page
mode burst four or higher devices are supported.
Asynchronous page mode burst two devices are not
supported and must be accessed normally.
Disabled (POR reset value).
Async page mode enabled (page length four).
Reserved, user software should not write ones to
reserved bits. The value read from a reserved bit is not
defined.
The value of the chip select polarity on power-on reset is
0.
Active LOW chip select.
Active HIGH chip select.
Reserved.
One CCLK cycle.
Two CCLK cycles.
Three CCLK cycles (POR reset value).
Reserved, user software should not write ones to
reserved bits. The value read from a reserved bit is not
defined.
