ISP1761
Hi-Speed USB OTG controller
Both the CPU interface logic and the USB Host Controller require access to the internal
ISP1761 RAM at the same time. The internal arbiter controls these accesses to the
internal memory, organized internally on a 64-bit data bus width, allowing a maximum
bandwidth of 240 MB/s. This bandwidth avoids any bottleneck on accesses both from the
CPU interface and the internal USB Host Controller.
7.3 Accessing the ISP1761 Host Controller memory: PIO and DMA
The CPU interface of the ISP1761 can be configured for a 16-bit or 32-bit data bus width.
When the ISP1761 is configured for a 16-bit data bus width, the upper unused 16 data
lines must be pulled up to V
CC(I/O)
. This can be achieved by connecting DATA[31:16] lines
together to a single 10 k
pull-up resistor. The 16-bit or 32-bit data bus width
configuration is done by programming bit 8 of the HW Mode Control register. This will
determine the register and memory access types in both PIO and DMA modes to all
internal blocks: Host Controller, Peripheral Controller and OTG Controller. All accesses
must be word-aligned for 16-bit mode and double-word aligned for 32-bit mode, where
one word = 16 bits. When accessing the Host Controller registers in 16-bit mode, the
