Datasheet  
5.3.18  
FREE_RUN—Free-Run 25MHz Counter  
Offset:  
9Ch  
Size:  
32 bits  
This register reflects the value of the free-running 25MHz counter.  
BITS  
DESCRIPTION  
TYPE  
DEFAULT  
31:0  
Free Running SCLK Counter (FR_CNT):  
RO  
-
Note:  
This field reflects the value of a free-running 32-bit counter. At reset  
the counter starts at zero and is incremented for every 25MHz  
cycle. When the maximum count has been reached the counter will  
rollover. Since the bus interface is 16-bits wide, and this is a 32-bit  
counter, the count value is latched on the first read. The  
FREE_RUN counter can take up to 160nS to clear after a reset  
event.  
Note:  
This counter will run regardless of the power management states  
D0, D1 or D2.  
5.3.19  
RX_DROP– Receiver Dropped Frames Counter  
Offset:  
A0h  
Size:  
32 bits  
This register indicates the number of receive frames that have been dropped.  
BITS  
DESCRIPTION  
TYPE  
RC  
DEFAULT  
31-0  
RX Dropped Frame Counter (RX_DFC). This counter is incremented every  
time a receive frame is dropped. RX_DFC is cleared on any read of this  
register.  
00000000h  
An interrupt can be issued when this counter passes through its halfway  
point (7FFFFFFFh to 80000000h).
