C8051T620/2-DK

8 Rev. 0.5

6. Example Source Code

Example source code and register definition files are provided by default in the

SiLabs\MCU\Examples\C8051T620_1_6_7_T320_3 or SiLabs\MCU\Examples\C8051T622_3_T326_7 directory

during IDE installation. These files may be used as a template for code development.

6.1. Register Definition Files

compiler_defs.h define all SFR registers and bit-addressable control/status bits. They are installed by default into

the SiLabs\MCU\Examples\C8051T620_1_6_7_T320_3 or SiLabs\MCU\Examples\C8051T622_3_T326_7

directory during IDE installation. The register and bit names are identical to those used in the C8051T620-21-26-

27_T320-3 or C8051T622-23_T326-27 data sheet.

6.2. Blinking LED Example

The example source files T620_Blinky.asm and T620_Blinky.c or T622_Blinky.asm and T622_Blinky.c show

examples of several basic C8051T62x functions. These include disabling the watchdog timer (WDT), configuring

the Port I/O crossbar, configuring a timer for an interrupt routine, initializing the system clock, and configuring a

GPIO port. When compiled/assembled and linked, these programs flash the green LED on the C8051T62x

Motherboard about five times a second using the interrupt handler with a timer.
