Bits 16:0 – TO[16:0] Timeout Value

The TO field size is limited to 8 bits if the ISO7816 logic is not implemented on some instances of FLEXCOM. The ISO7816 logic is implemented if it is possible to write FLEX_US_MR.MAX_ITERATIONS=1 (a read operation must be performed after the write operation to check that MAX_ITERATIONS equals 1).

Value	Description
0	The receiver timeout is disabled.
1–131071	The receiver timeout is enabled and the timeout delay is TO × bit period.
