Advanced Digital I/O (aDIO), and Advanced Analog I/O (aAIO). RTD has gone the extra mile to include additional advanced features for maximum flexibility. These include a SATA Disk Chip socket that allows flash drive with a standard SATA interface to be attached to the board, either socketed or soldered. -
Page 11: Enhanced Intel Speedstep (Core 2 Duo Only)
Wake-on-aDIO RTD’s exclusive aDIO™ is 12 digital bits configured as 8 bit-direction programmable and 4-bit port-direction programmable I/O, plus 2 strobe inputs giving you any combination of inputs and outputs. Match, event, and strobe interrupt modes mean no more wasting valuable processor time polling digital inputs. - Page 12 The aAIO also provides interrupts on threshold crossing. A high and low threshold can be set for each channel. After sampling is started, an interrupt can be generated if any of the signals cross the threshold. This removes some of the CPU load for simple monitoring tasks. A DMA engine with a scatter-gather table allows efficient, robust handling of data.

Page 67: I/O Address Map
I/O Address Map As with all standard PC/104 boards, the I/O total I/O space is 64k in size. However, because early processors only addressed 0 address lines (SA0–SA9), the first 1k is used for legacy I/O devices. Any ISA add-on modules you install must therefore use I/O addresses in the range of 0–1023 (decimal) or 000–3FF (hex). -
Page 68: Hardware Interrupts
Hardware Interrupts Note If you add any expansion modules or other peripherals to the system, you must ensure they do not use interrupts needed by the cpuModule, or malfunctions will occur. The CMA22M cpuModule supports the standard PC interrupts listed in Table 40. Interrupts not in use by hardware on the cpuModule itself are listed as available. -
Page 69: Non-Standard Serial Port Modes
Non-Standard Serial Port Modes It is possible to change the input clock rate for the UARTs of the cpuModule by selecting the Serial Port Baud Rates option in the Serial Port Configuration menu of the BIOS Setup. Changing the option from Normal to Non-Standard will allow the serial port to operate at higher speeds. -
Page 70: Advanced Digital I/O Ports (Adio™)
This board supports 12 bits of TTL/CMOS compatible digital I/O (TTL signaling). These I/O lines are grouped into two ports, Port 0 and Port 1. Port 0 is bit programmable; Port 1 is byte programmable. Port 0 supports RTD’s Advanced Digital Interrupt modes. The three modes are strobe, match and event. Strobe mode generates an interrupt and latches Port 0 when the strobe input transitions from low to high. - Page 71 Table 45 DIO-Control I/O Address 9C3h—Read Access Strobe 1 Status Strobe 0 Status 0 = no strobe 0 = no strobe Multi-Function 1 = strobe Digital IRQ Mode 1 = strobe Register Select 00 = Disabled 00 = clear mode 01 = strobe Mode Digital IRQ Status Port 1 Direction...

Page 74: Real Time Clock Control
This RTD cpuModule uses onboard flash to store user BIOS settings. To preserve compatibility with traditional PCs, the RTD Enhanced BIOS also mirrors the user settings from flash in CMOS. Therefore, the contents of CMOS may be overwritten at boot time, and should be treated as “read only”. - Page 75 Altering the contents of any unlisted RTC register may interfere with the operation of your cpuModule.
