19 Target JTAG
Frequency
The programmer supports a user-defined JTAG frequency:
•
SLOW JTAG: 0 – 833 kHz
•
FAST JTAG: approx 1.4 MHz
20 JTAG Programming
Modes
The programmer supports the following JTAG modes:
•
Single JTAG device connected to programmer
•
Multiple JTAG devices connected in a JTAG Chain
•
JTAG ID can be verified for both Atmel AVR,
AT91SAM7 and non-Atmel JTAG devices
•
JTAG chain validation is also supported
21 I2C Frequency
The programmer supports a user-defined I2C frequency:
•
SLOW I2C: 0 – 400 kHz
•
Supports ISP programming of both 100 kHz and 400
kHz I2C Serial EEPROMs
22 Target UART Speed
•
This is the Communications Speed (BAUD rate) from
the programmer to the Target Device when
communicating via a Boot Loader.
•
The BAUD rate is configurable from 1,200 to 115
kBaud.
•
This settings is completely independent from the BAUD
rate settings for the PC communicating with the
programmer.
23 ISP Headers
The programmer can support any ISP header by simply
plugging in the relevant ‘ISPnano Pin-out Converter Module’.
The currently supported ISP Headers are as follows:
•
Atmel 10-way (SPI)
•
Atmel 6-way (SPI)
•
Atmel 10-way (JTAG)
•
Atmel 20-way (JTAG) for AT91SAM7 microcontrollers
•
Equinox 10-way (SPI+UART)
•
Fast-connect wire connectors
24 Frequency generator
output (SCK2)
Programmer can output a configurable square wave frequency
on the SCK2 pin. This is used to clock the Target Device in the
absence of a Target Oscillator.
•
Frequency range: 167kHz – 1.8432 MHz
25 AVR On-chip
Oscillator Calibration
The programmer can generate a suitable square wave for use
with ‘AVR on-chip oscillator calibration’.
