Introduction

This module contains APIs to program and use the FSI module.

Files
file	fsi/v0/fsi.h
	Header file containing various enumerations, structure definitions and function declarations common for both the FSI TX and FSI RX IP.

Macros

Macro Definition Documentation

#define FSI_MAX_LEN_NWORDS_DATA ((uint16_t)0xFU)

Maximum data length(16 words) for user/software defined data frame.

#define FSI_MAX_VALUE_USERDATA ((uint16_t)0xFFU)

Maximum value for user data field (8 bits)

#define FSI_MAX_VALUE_BUF_PTR_OFF ((uint16_t)0xFU)

Maximum value of Buffer pointer offset (4 bits)

#define FSI_CTRL_REG_KEY ((uint16_t)0xA5U)

Key value for writing some FSI TX/RX registers.

#define FSI_DATA_WIDTH_1_LANE ((uint32_t)0x0U)

1 lane data width

#define FSI_DATA_WIDTH_2_LANE ((uint32_t)0x1U)

2 lane data width

#define FSI_PINGTIMEOUT_ON_HWSWINIT_PING_FRAME ((uint32_t)0x1U)

Ping timeout can reset and restart both on hardware or software initiated frame being sent out also based on which mode is selected

typedef uint32_t FSI_DataWidth

Data lines used for transmit/receive operation.
