Clock source
Two clock sources are available on the STM32100B-EVAL board for the STM32F100VBT6
microcontroller and RTC.
Reset source
The reset signal of the STM32100B-EVAL board is active low and the reset sources include:
Table 4.
Audio
The STM32100B-EVAL board supports playback based on a speaker on the board. This
can be disabled or enabled by jumpers JP1 and JP2. The audio volume can be adjusted
using the potentiometer RV1. See
Table 5.
Serial Flash
A 128 Mbit serial Flash connected to SPI1 of the STM32F100VBT6 microcontroller shares
the same SPI port with the MicroSD Card using a different chip select signal. Serial Flash
chip select is managed by the standard I/O port PD9.
Jumper
Jumper
X1, 32 KHz crystal for embedded RTC
X2, 8 MHz crystal with socket for the STM32F100VBT6 microcontroller. It can be
removed from the socket when the internal RC clock is used.

Bootloader_Reset signal from the RS-232 connector CN10 pin 1 (DCD) is connected
to RESET# of the STM32F100VBT6 when JP5 is closed.
This configuration is used for the boot loader application only.
Default setting: Not fitted
Audio power amplifier TS4990IST is forced on standby mode when JP1 is fitted.
Default setting: Not fitted
The DAC _OUT(PA4) is connected to speaker circuit when JP2 is closed.
Default setting: Fitted
