INBUFM 
IN Buffer Monitor 
Indicates the pertinent FIFO buffer status when the 
pertinent pipe is in the transmitting direction.  
0:  There is no data to be transmitted in the buffer 
memory. 
1:  There is data to be transmitted in the buffer 
memory. 
When the pertinent pipe is in the transmitting 
direction (DIR = 1), this module sets this bit to 1 
when at least one FIFO buffer plane of data has 
been written. 
This module sets this bit to 0 when this module 
completes transmitting the data from the FIFO buffer 
plane to which all the data has been written. In 
double buffer mode (DBLB = 1), this module sets this 
bit to 0 when this module completes transmitting the 
data from the two FIFO buffer planes before one 
FIFO buffer plane of data has been written. 
This bit indicates the same value as the BSTS bit 
when the pertinent pipe is in the receiving direction 
(DIR = 0).
