CAMPBELL, Calif.  July 1, 2003  Nohau Corporation announced today that it offers full-featured emulator and BDM support for the MC9S12E128 microcontroller, of the HCS12 family, from Motorola Inc.’s Semiconductor Product Sector. Nohau’s emulator brings sophisticated debugging features to assist users in their development, and getting product to market faster.

“Development support from companies such as Nohau is critical to the success of our HCS12 family,” said Kevin Kilbane, Strategic Marketing Manager for Motorola’s 8/16 Bit Products Division.  “Not only does Nohau provide an excellent intuitive development environment for our HCS12 microcontroller products, but they also have great international presence to support newly developing regions.”

The MC9S12E128 full-emulator operates to a bus speed of 30MHz at both 5V and 3.3V. Users can start/stop, single-step, set trace triggers, examine/modify memory and C variables and perform all other emulator functions. The use of all the E128 features and resources is supported. Large emulation RAM can be used to replace the internal FLASH, to allow an easy debug process, and to develop applications for the future E256, E64 and E32 family members today. An unlimited number of page-aware software and hardware breakpoints are available.

Motorola’s MC9S12E128 is the first HCS12 part designed from the ground-up for the general market. It is a 112 / 80 pin MCU, which includes a 16-bit HCS12 CPU, 128K FLASH, 8K RAM, three SCI, one SPI and three 4-channel IC/OC timers. It also includes a 16-channel, 10-bit A/D, two 1-channel, 8-bit D/As, a 6-channel PWM, a 6-channel PWM with fault protection, an IIC Bus, 48 digital I/Os, 18 with interrupt and wakeup capability, system resource mapping, PLL, interrupt control, and bus interfacing. It accepts 3 V to 5.5V external supply range.

The Nohau emulator enables testing and debugging of all E128 operating modes, including ones that are not possible, or are very limited, using simpler BDM emulators. These include: Going through and out of Reset and COP Watchdog Reset, STOP and WAIT power-down modes, clock loss limp-home mode, and full internal PLL support for frequent speed changes. These events can also be clearly recorded in the trace.
 
A hardware trace is optional, and allows recording up to 131,000 frames of E128 instruction execution and bus activity. The trace is equipped with powerful triggers and a filter, to set complex conditions to stop upon, and focus the trace to record only relevant information. The trace can start, stop and be re-programmed without ever stopping or slowing down the E128 execution. This ability is very important to debug applications that cannot be stopped (for example motor control).

“Nohau is pleased to offer this tool in a timely manner, enhancing Nohau’s support of all HCS12 based derivatives,” said Olle Hallengren, president of Nohau Corporation. “This continues our alliance with Motorola extending the number of supported derivatives for the HCS12 family.”
