JTAG
Frequency
With standard ‘SFM Module’ fitted:
The programmer supports a user-defined JTAG frequency:
•
SLOW JTAG: 0 – 833 kHz
With ‘SFM-MAX V1.2 or V1.3’ Module fitted:
•
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 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 ‘EQ-IOCON’ I/O Connector Module.
The currently supported ISP Headers are as follows:
•
Atmel 10-way (SPI)
•
Atmel 6-way (SPI)
•
Atmel 10-way (JTAG)
•
Equinox 10-way (SPI+UART)
•
Fast-connect
wire
connectors
Please refer to the separate manual ‘PPM3 I/O Connector
Modules’ for full details of each module and the connection
mechanisms available.
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
If the programmer is fitted with either the ‘CALCON’ or ‘EQ-
SFM-V1.3’ module, then it can be used to calibrate the internal
