SYNCHRONOUS CARDS
If bit SAN (Synchronous/Asynchronous-N) is set, the
software can operate with synchronous cards; the
information available on the I/O line is copied on data bit 0
of the data bus without entering the UART when either
registers SIR or SOR are selected. At the end of a
transmission in synchronous mode, it is necessary to
switch back to synchronous reception mode by reading
register SIR.
The synchronous clock may be controlled by selecting
CLK STOP HIGH or STOP LOW. Contacts C4 and C8
may be controlled by ports P34 and P35 (operation
depends on synchronous card type).
Synchronous Input Register (SIR; address 3; read only)
When this register is selected, I/O is copied on data bit 0
(P40) and may be read by the controller.
Synchronous Output Register (SOR; address 3; write
only)
When this register is selected, I/O is copied on data bit 0
(P40) on the falling edge of EN.
