registers of the enabled transmitters or to the time slot register (TSR). TEDE is cleared when
the DSP writes to all the transmit data registers of the enabled transmitters, or when the DSP
writes to the TSR to disable transmission of the next time slot. If TIE is set, an ESAI transmit
data interrupt request is issued when TEDE is set. Hardware, software, ESAI individual, and
STOP reset clear TEDE.

SAISR Transmit Odd-Data Register Empty (TODE) - Bit 17

When set, TODE indicates that the enabled transmitter data registers became empty at the
beginning of an odd time slot. Odd time slots are all odd-numbered slots (1, 3, 5, etc.). Time
slots are numbered from zero to N-1, where N is the number of time slots in the frame. This
flag is set when the contents of the transmit data register of all the enabled transmitters are
transferred to the transmit shift registers; it is also set for a TSR disabled time slot period in
network mode (as if data were being transmitted after the TSR was written). When set, TODE
indicates that data should be written to all the TX registers of the enabled transmitters or to the
time slot register (TSR). TODE is cleared when the DSP writes to all the transmit data
registers of the enabled transmitters, or when the DSP writes to the TSR to disable
transmission of the next time slot. If TIE is set, an ESAI transmit data interrupt request is
issued when TODE is set. Hardware, software, ESAI individual, and STOP reset clear TODE.
