6.5. LED Control
The CP2200/1 can be used to control link status and activity LEDs. The CP2200 (48-pin TQFP) has two push-pull
LED drivers that can source up to 10 mA each. The CP2201 (28-pin QFN) has a single push-pull LED driver that
turns the LED on or off based on the link status and blinks the LED when activity is detected on a good link. Table 9
shows the function of the LED signals available on the CP2200/1.
Figure 12 shows a typical LED connection for the CP2200. The CP2201 uses an identical connection for the LA
(link/activity) pin. The LED drivers are enabled and disabled using the IOPWR register on page 45.
