Technical Summary
2-11
2.9 Reset
Logic is provided on the 56F805 to generate a clean power-on RESET signal. Additional,
reset logic is provided to support the RESET signals from the JTAG connector, the
Parallel JTAG Interface and the user RESET push-button; see
Figure 2-7. Schematic Diagram of the RESET Interface
2.10 Power Supply
The main power input, 12V DC at 4.0A, to the 56F805EVM is through a 2.1mm coax
power jack. A 4.0Amp power supply is provided with the 56F805EVM; however, less
than 500mA is required by the EVM. The remaining current is available for user motor
control applications when connected to an optional motor power stage board. The
56F805EVM pr3.3V DC voltage regulation for the device, memory, D/A, CAN,
parallel JTAG interface and supporting logic; refer to
. Power applied to the
56F805EVM is indicated with a Power-On LED, referenced as LED10.
