TXCNT
Transmit Counter. Read-only bits which read the number of bytes in the transmit buffer (0 to 128).
bits 70
TXFLUSH
Flush Transmit FIFO. This bit is write-only. When set, the SPI transmit pointer is set equal to the FIFO Output pointer.
bit 7
This bit is 0 for a read operation.
CLK_EN
SCLK Driver Enable.
bit 5
0: Disable SCLK Driver (Master Mode)
1: Enable SCLK Driver (Master Mode)
DRV_DLY
Drive Delay (refer to DRV_EN bit).
bit 4
0: Drive Output Immediately
1: Drive Output After Current Byte Transfer
DRV_EN
Drive Enable.
bit 3
DRV_DLY
DRV_EN
MOSI or MISO OUTPUT CONTROL
0
Tristate immediately.
0
1
Drive immediately.
1
0
Tristate after the current byte transfer.
1
Drive after the current byte transfer.
TXIRQ
Transmit IRQ Level. Write-only bits.
bits 20
000
Generate IRQ when Transmit Count = 1 or less.
001
Generate IRQ when Transmit Count = 2 or less.
010
Generate IRQ when Transmit Count = 4 or less.
011
Generate IRQ when Transmit Count = 8 or less.
100
Generate IRQ when Transmit Count = 16 or less.
101
Generate IRQ when Transmit Count = 32 or less.
110
Generate IRQ when Transmit Count = 64 or less.
111
