Typedef Documentation

◆ FSI_ECCComputeWidth

typedef uint32_t FSI_ECCComputeWidth

ECC Computation width - 16 bit or 32 bit.

◆ FSI_InterruptNum

typedef uint32_t FSI_InterruptNum

Interrupt lines supported in FSI.


Any event on FSI TX or RX can be enabled to trigger interrupt on 2 interrupt lines to CPU/CLA - INT1 and INT2

◆ FSI_FrameType

typedef uint32_t FSI_FrameType

FSI frame type.

Three frame types exist- Ping: Used for checking line integrity, can be sent by software or automatically by hardware. Error: Used typically during error conditions or when one side wants to signal the other side for attention. Data: Two subtypes exist based on data-length- a) Fixed (1/2/4/6 words) b) Nwords Software programs number of data words


4 bit code for frame types - 0x1, 0x2 and 0x8 to 0xE are reserved

◆ FSI_PingTimeoutMode

typedef uint32_t FSI_PingTimeoutMode

FSI ping timeout mode.
