ISP1183
Low-power USB Peripheral Controller with DMA
12.3.2 DMA Conguration register (R/W: F1h/F0h)
This command denes the DMA conguration of the ISP1183 and enables or disables
DMA transfers. The command accesses the DMA Conguration register, which consists of
2 bytes. The bit allocation is given in Table 32. A bus reset will clear bit DMAEN (DMA
disabled), all other bits remain unchanged.
Code: F0h/F1h — write or read DMA Conguration
Transaction — write or read 2 bytes
[1]
Unchanged by a bus reset.
12.3.3 DMA Counter register (R/W: F3h/F2h)
This command accesses the DMA Counter register, which consists of 2 bytes. The bit
allocation is given in Table 34. Writing to the register sets the number of bytes for a DMA
transfer. Reading the register returns the number of remaining bytes in the current
transfer. A bus reset will not change programmed bit values.

Description

CNTREN
Logic 1 enables the generation of an EOT condition, when the DMA
Counter register reaches zero. Bus reset value: unchanged.
14
SHORTP
Logic 1 enables short or empty packet mode. When receiving (OUT
endpoint) a short or empty packet, an EOT condition is generated. When
transmitting (IN endpoint), this bit should be cleared. Bus reset value:
unchanged.

EPDIX[3:0]
Indicates the destination endpoint for DMA, see Table 7.
3
DMASTART
Writing logic 1 starts a DMA transfer. Logic 0 forces the end of an
ongoing DMA transfer. Reading this bit indicates whether DMA is started
(0 = DMA stopped, 1 = DMA started). This bit is cleared by a bus reset.

BURSTL[1:0] Selects the DMA burst length:
00 — single-cycle mode (1 byte)
01 — burst mode (4 bytes)
10 — burst mode (8 bytes)
11 — burst mode (16 bytes)
Bus reset value: unchanged.
