Bit | Field | Type | Reset | Description |
---|---|---|---|---|
15 | START | R/W | 0h | Start Transmission bit This bit will cause the FSI to start transmitting the next frame. 0h[R/W] = Writing a 0 to this bit will have no effect. 1h[R/W] = Start the next transmission. This bit will be cleared by hardware. |
14:8 | RESERVED_1 | R | 0h | Reserved |
7:4 | N_WORDS | R/W | 0h | Number of Words to be Transmitted This field defines the number of words which will be transmitted in a DATA_N_WORD frame. This is a user-defined field that must match the corresponding field in the receiver. Set this bitfield to be one less than the number of words to be transmitted. 0h[R/W] = 1 data word frame [16-bit data]. 1h[R/W] = 2 data word frame [32-bit data]. .. Fh [R/W] = 16 data word frame [256-bit data]. |
3:0 | FRAME_TYPE | R/W | 0h | Transmit Frame Type This field determines the type of frame that will be transmitted next. 0000b[R/W] = Ping Frame. This frame can be sent either by software or automatically by hardware. 0100b[R/W] = DATA_1_WORD Frame. One word data frame [16-bit data]. 0101b[R/W] = DATA_2_WORD Frame. Two word data frame [32-bit data]. 0110b[R/W] = DATA_4_WORD Frame. Four word data frame [64-bit data]. 0111b[R/W] = DATA_6_WORD Frame. Six word data frame [96-bit data]. 0011b[R/W] = DATA_N_WORD Frame. The N_WORDS field will determine the number of words [1 to 16] to be sent. Both the transmitter and receiver must have the same value programmed. 1111b[R/W] = Error Frame. This frame can be used during error conditions or any condition where the transmitter wants to notify the receiver of a high priorty status. However, the user software is at liberty to use this for any purpose. 0001b 0010b and 1000bthrough 1110bare Reserved and should not be used. |
