Figure 1 – TD243 Architectural Block Diagram
USB/OTG Host logic blocks:
The USB Host Controller Logic, the host Serial Interface Engine (SIE) and the root
hub are responsible for the fully complaint (not reduced) USB host of the TD243 - supporting transfer level user
interface, scheduling/processing transactions, and monitoring/handling port events.
USB/OTG Peripheral logic blocks:
The USB Peripheral Controller Logic, together with the peripheral SIE,
manages all low-level USB peripheral protocols upon which a fully compliant full speed USB peripheral is operated.
Direct Memory Access:
Two DMA channels allow fast data movement between the application and the TD243
with minimum intervention from the microprocessor. Programmed accesses to the TD243 through DMA and those
through memory mapped, programmed I/Os can be interleaved.
Interrupt Handling:
Interrupts from the TD243 to a microprocessor are minimum, as an interrupt is generated only
at the end of a USB transfer (for both host and peripheral), which can have a size of up to 4 Mbytes*. Moreover, an
