... The ARM standard In-Circuit Emulation (ICE) debug interface is supported via the ICE port of the ATR0620. 3. PDC2 The ATR0620 has an 8-channel PDC2 dedicated to the three on-chip USARTs and to the SPI. One PDC2 channel is connected to the receiving channel and one to the transmitting channel of each peripheral. ...

... External sources can be programmed to be positive or negative edge triggered or high- or low- level sensitive. 6. PIO2: Parallel I/O Controller The ATR0620 features 32 programmable I/O lines. The I/O lines are multiplexed with on-chip peripheral I/O signals in order to optimize the use of available package pins. The PIO2 controller provides an internal interrupt signal to the Advanced Interrupt Controller (AIC). ...

... SPI without CPU intervention for maximum real-time processing throughput. 9. WD: Watchdog Timer The ATR0620 features an internal watchdog timer, which can be used to guard against system lock-up if the software becomes trapped in a deadlock. The watchdog timer can be programmed to generate an interrupt or an internal reset. ...

... The GPS correlator processes GPS signal data to acquire the GPS satellite signals using a model of the satellite codes and multiply/accumulate circuits (correlators) to spread the signal to a bandwidth low enough to detect it above thermal noise. 16. GPS Accelerator The ATR0620 features an accelerator which reduces the time to identify the correct GPS signal. ATR0620 [Preliminary ...
