27.15:6 – LED Pin Configuration
Each of the five LED pins on each port of the VSC8211 can be configured for one of four functions. These functions are different
for each LED pin. Bits 27.15:6 are used to select the function for each LED pin. The reset value of these bits is set by the LED
configuration bits in the CMODE hardware configuration. If
‘Force off’ and the LED setting ‘11’ becomes ‘Force on’.
27.5 – LED Pulse-Stretch/Blink Rate
The Collision, Activity, Tx and Rx LED functions can be set to either blink at a constant rate or visibly flash through the use of
pulse-stretching. The blink rate and pulse-stretch length are set with this bit.
27.4 – LED Pulsing Enable
When bit 27.4 is set to “1”, all LED outputs are pulsed at a 5kHz rate with 20% duty cycle in order to save power.
27.3 – LED Pulse-Stretch / Blink Select
When bit 27.3 is set to “1”, Collision, Activity, Tx and Rx LED functions will be pulse-stretched. When bit 27.3 is cleared, these
LED functions will blink at a constant rate. Bit 27.5 are used to select the pulse-stretch / blink rate.
27.2 – LED Link/Activity Behavior
When bit 27.2 is set to “0”, the link status LED function will blink or flash when activity is present. Blink / flash behavior is
selected by bits 27.3 and 27.5.
27.1 – LED Linkxxxx/Activity Behavior
When bit 27.1 is set to “0”, all linkxxxx status LED functions (Link10, Link100, Link1000, Link10/100, Link100/1000) will blink or
flash when activity is present. Blink / flash behavior is selected by bits 27.3 and 27.5.
27.0 – LED Duplex/Collision Behavior
When bit 27.0 is set to “1”, the Duplex LED function indicates duplex status only. When bit 27.0 is cleared, the Duplex function
will blink or flash when collision is present. Blink / flash behavior is selected by bits 27.3 and 27.5.
