5.4.7
High-End Timer Transfer Unit (HTU)
A High End Timer Transfer Unit (HTU) can perform DMA type transactions to transfer N2HET data to or
from main memory. A Memory Protection Unit (MPU) is built into the HTU.
5.4.7.1
Features
CPU and DMA independent
Master Port to access system memory
8 control packets supporting dual buffer configuration
Control packet information is stored in RAM protected by parity
Event synchronization (HET transfer requests)
Supports 32 or 64 bit transactions
Addressing modes for HET address (8 byte or 16 byte) and system memory address (fixed, 32 bit or
64bit)
One shot, circular and auto switch buffer transfer modes
Request lost detection
