Boot on NCS0
26
AT91X40 Series
Depending on the device and the BMS pin level during the reset, the user can select
either an 8-bit or 16-bit external memory device connected on NCS0 as the Boot Mem-
ory. In this case, EBI_CSR0 (Chip Select Register 0) is reset at the following
configuration for chip select 0:
•
•
Byte access type and number of data float time are respectively set to Byte Write
Access and 0. With a non-volatile memory interface, any values can be programmed for
these parameters.
Before the remap command, the user can modify the chip select 0 configuration, pro-
gramming the EBI_CSR0 with exact boot memory characteristics. the base address
becomes effective after the remap command, but the new number of wait states can be
changed immediately. This is useful if a boot sequence needs to be faster.
8 wait states (WSE = 1, NWS = 7)
8-bit or 16-bit data bus width, depending on BMS
