C8051F530A-DK
7.3. Switches and LEDs
Four switches are provided on the target board.
Switch RESET_A is connected to the RESET pin of the C8051F530A A-Side (U2).
Switch RESET_B is connected to the RESET pin of the C8051F530A B-Side (U1).
Pressing RESET_A or RESET_B puts the attached device into its hardware-reset state.
Switches P1.4_A and P1.4_B are connected to the C8051F530A parts (U1 and U2) general purpose I/O (GPIO)
pins through headers. Pressing P1.4_A or P1.4_B generates a logic low signal on the port pin of the respective
microcontroller.
Remove the shorting block from the header to disconnect P1.4_A or P1.4_B from the port pins. The port pin
signals are also routed to pins on the J1 and J2 I/O connectors. See Table 1 for the port pins and headers
corresponding to each switch.
Four LEDs are also provided on the target board. The red LED labeled PWR is used to indicate a power
connection to the target board. The green LEDs labeled D1 and D2 are connected to the C8051F530A's GPIO pins
through headers. Remove the shorting blocks from the headers to disconnect the LEDs from the port pins. The port
pin signals are also routed to pins on the J1 and J2 I/O connectors. The red LED labeled USB ACTIVE is used to
indicate that the CP2102 USB-to-UART bridge is properly connected to a PC and is ready for communication. See
Table 1 for the port pins and headers corresponding to each LED.
A potentiometer (R32) is provided on the target board. Header J8 connects the potentiometer to +5 V and header
J6 connects the potentiometer to the P1.2_A pin of the U2 A-Side C8051F530A microcontroller.
