ESAI_1 TIME SLOT REGISTER (TSR_1)
The write-only Time Slot Register (TSR_1) 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_1 has been written. The Transmitter External Buffer Enable pin (FSR_1 pin when
SYN=1, TEBE=1, RFSD=1) disables the external buffers during the slot when the TSR_1
register has been written.
11.3.13
TRANSMIT SLOT MASK REGISTERS (TSMA_1, TSMB_1)
The Transmit Slot Mask Registers (TSMA_1 and TSMB_1) 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_1 and TSMB_1 should each be considered as containing half a 32-bit register TSM_1.
See Figure 11-11 and Figure 11-12. Bit number N in TSM_1 (TS**) is the enable/disable
control bit for transmission in slot number N.
