Description
Reserved
Page Boundary (PAGE_BDRY): Specifies the boundary limit for sync or async burst
reads. This is defined in terms of the least significant AHB address bit which must
remain constant for the burst to continue.
Extend (EXT): When set, CS1 or CS3 becomes MA[24] and CS0 address space is
32MB. When cleared, CS1 or CS3 used normally. Note: Can use CS1 only if there is no
SDRAM.
Reserved
Page Mode (PAGE_EN): When set, enables asynchronous page reads for this device.
FLCLK Based Timing Enable (FLCLK_BTEN): When set, enables the clock divider
for this external device. Uses the flclk divider to provide longer clock cycles for slow
peripherals. When cleared, flclk Timing disabled.
READY Pin Polarity (RDY_POL): When set, ‘1’ means ready. When cleared, VSS
means ready.
READY Pin Enable (RDY_EN): When set, READY indicates cycle completion. When
cleared, READY pin ignored
Byte Control Style (BYTE_STYLE): Specifies the style of the control bits used. This
is used to provide a seamless solution for interfaces:
Data Bus Width (WDTH): When cleared, external device width is 8 bits. When set,
external device width is 16-bits.

16-bit using 2xWE and no BE, 16-bit using 1xWE and 2xBE, 8-bit using 1xWE
When cleared, nWEU=nWEU, nWEL=nWEL, A[0] = unused, held low
When set, nWEU=nBEU, nWEL=nEW, A[0] = nBEL
8-bit device:
When cleared, nWEU= unused, held high, nWEL=nWE, A[0] = A0
When set, nWEU=nBE, nWEL=nWE, A[0] = A0
and no BE, 8-bit using 1xWE and 1xBE16-bit device:
