Description

OCTOSPI device configuration register 2

Fields

PRESCALER

Clock prescaler

0 (B_0x0): Fless thansub>CLKless than/sub> = Fless thansub>KERNELless than/sub>, kernel clock used directly as OCTOSPI CLK (prescaler bypassed).

1 (B_0x1): Fless thansub>CLKless than/sub> = Fless thansub>KERNELless 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.
