TCB Storage

TCB Storage
This section lists all the different TCB memory allocations used for DMA
chaining on the peripherals. Note that all TCBs must be located in inter-
nal memory.

Serial Port TCB

The serial ports support single and chained DMA.

Parallel Port TCB

The parallel port interface supports both single and chained DMA. How-
ever, unlike the serial ports, programs cannot insert a TCB in an active
chain. Table 2-14
