Clocking; Reset Control; Debug Jtag Interface; Serial Wire Debugger Interface - ST STM32303C-EVAL User Manual

Functional description of the evaluation board
1.2

Clocking

Two clock sources are available on the STM32303C-EVAL evaluation board:
●
32 KHz crystal for embedded RTC
●
8 MHz crystal for the STM32F30x/31x main clock system
1.3

Reset control

The reset can be generated by hardware or software:
●
Reset button: activates the RESET input when pressed
●
JTAG reset
1.4

Debug JTAG interface

Software debug is done via the standard ARM
displacement connector) for connection to the standard ARM host interface.
1.5

Serial wire debugger interface

The Serial Wire Debug Port (SWD-DP) provides a 2-pin (clock + data) interface to the AHP-
AP port.
1.6

Embedded ST-LINK

An ST-LINK is integrated on the board as an embedded in-circuit debugger and programmer
for the STM32F30x/31x MCU.

LCD

A TFT color LCD module is mounted on the STM32303C-EVAL board. It is interfaced
through the embedded SPI peripheral.
1.7.2

LEDs

Four general-purpose LEDs are available. They are used as a display.
