ESAI TIME SLOT REGISTER (TSR)
The write-only Time Slot Register (TSR) is effectively a null data register that is used when
the data is not to be transmitted in the available transmit time slot. The transmit data pins of all
the enabled transmitters are in the high-impedance state for the respective time slot where
TSR has been written. The Transmitter External Buffer Enable pin (FSR pin when SYN=1,
TEBE=1, RFSD=1) disables the external buffers during the slot when the TSR register has
been written.
10.3.12
TRANSMIT SLOT MASK REGISTERS (TSMA, TSMB)
The Transmit Slot Mask Registers (TSMA and TSMB) are two read/write registers used by
the transmitters in network mode to determine for each slot whether to transmit a data word
and generate a transmitter empty condition (TDE=1), or to tri-state the transmitter data pins.
TSMA and TSMB should each be considered as containing half a 32-bit register TSM. See
Figure 10-15 and Figure 10-16. Bit number N in TSM (TS**) is the enable/disable control bit
for transmission in slot number N.
