WRAPSIZE=B_0x0, PRESCALER=B_0x0
XSPI device configuration register 2
PRESCALER | Clock prescaler 0 (B_0x0): F less than sub>CLK less than /sub> = F less than sub>KERNEL less than /sub>, kernel clock used directly as XSPI CLK (prescaler bypassed). In this case, if the DTR mode is used, it is mandatory to provide to the XSPI a kernel clock that has 50% duty-cycle. 1 (B_0x1): F less than sub>CLK less than /sub> = F less than sub>KERNEL less than /sub>/2 |
WRAPSIZE | Wrap size 0 (B_0x0): wrapped reads are not supported by the memory. 2 (B_0x2): external memory supports wrap size of 16 bytes. 3 (B_0x3): external memory supports wrap size of 32 bytes. 4 (B_0x4): external memory supports wrap size of 64 bytes. 5 (B_0x5): external memory supports wrap size of 128 bytes. |
