Supports sample data input/output by DMA transfer
from the TX4937 on-chip peripheral circuits and issues interrupt requests to the TX49/H3 core.
This controller has a 16-bit flag register that generates interrupt requests to an external device or
the TX49/H3 core.

The TX4937 has an on-chip 2-channel asynchronous serial I/O interface (full duplex UART)
The TX4937 has an on-chip 3-channel timer/counter
The TX4937 has a 16-bit parallel I/O port (8 bits of which are shared with CB[7:0])
The TX4937 on-chip AC-link Controller can connect and manipulate audio and/or modem
The Interrupt Controller built into the TX4937 receives interrupt requests and external interrupts
