Table 26-22. Transfer Status Current Buffer (TSCB) Field Descriptions (continued)
Bit Field Value Description
8 IDLE Detects Transfer State Machine State IDLE.
Will be set if the transfer unit state machine is in IDLE state and ready to start the next transfer,
but nothing is requested.
0 IDLE state is not reached since last clear.
1 IDLE state is reached.
7 Reserved 0 Reads return 0. Writes have no effect.
6-0 BN 0-7Fh Buffer number.
7-bit value of buffer number, which is currently in transfer. If state machine enters IDLE mode the
last transferred buffer number is shown.
