Description
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 software (or DMAC) completes writing data to
at least one FIFO buffer plane.
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 software
(or DMAC) completes writing data to one FIFO buffer
plane.
This bits indicates the same value as the BSTS bit
when the pertinent pipe is in the receiving direction
(DIR = 0).
