Field Bits Type Description
RDC [4:0] rh Ready Delay Counter
This bit field counts TCLK periods after the end of a
frame transmission. When the TVALID signal goes to
low level, RDC is cleared to zero and starts counting up
the TCLK clock periods until a TREADY high level is
detected (see Page 23-22).
APN [6:5] rh Answer Pipe Number
This bit field is written by the MLI receiver with the Pipe
Number of a received Read Frame. APN is used by an
Answer Frame that is transmitted as response to the
Read Frame.
00

Pipe 0 is used in Answer Frame.

Pipe 3 is used in Answer Frame.
PE 7rhParity Error Flag
This bit is set if a transmitter parity error condition is
detected by the transmitter after a frame transmission.
PE is cleared by hardware when a frame has been
transmitted without a parity error (see Page 23-42). Bit
PE can be cleared by software via bit SCR.CTPE.
