2.4.2.3 INTMSK—Interrupt Mask (Transparent Mode)
Each event dened in the interrupt circular queue entry maps directly to a bit in INTMSK
as shown in Figure 2-13. There is one mask bit for each event—UN (bit 11), BSY (bit 13),
TXB (bit 14) and RXB (bit 15). Bits that do not map to an event are reserved. Reserved bits
must be set to zero.
0 = No interrupt request is generated and no new entry is written in the circular
interrupt table.
1 = Interrupts are enabled.
This register is initialized by the host before operation.

Note: For the 68360, the bit numbering is reversed. See Appendix A for more information.

2.4.2.4 TRNSYNC—Transparent Synchronization
In transparent mode, the TRNSYNC register controls the synchronization for single time
slots or superchannel applications.
Note
This register has no meaning if the SYNC bit in the channel
mode register (CHAMR) is cleared (0).
When sending a transparent message over several time slots, it is necessary to know in
which time slot the rst byte of data appears.
The TRNSYNC word-length register is divided into two parts with the high byte
controlling the rst received time slot and the low byte controlling the transmitter
synchronization.
