Preliminary specification
Error correction and host interface IC for
CD-ROM (SEQUOIA)
SAA7385
Table 31 BRGSEL field description
Table 32 UART special control register: 0xF09E; note 1
Note
1. Register 0xF09E allows the 80C32 UART clock to be derived from 16.945 MHz. This external UART clock is required
for reliable operation of the UART if the 80C32 is used for other functions during the transfer.

not specified
INVQ
inverts all Q-channel information if set
INVSUBC
inverts all sub-code information if set
EVENPAR
selects even parity for S2B UART is set
LOCK
read only information; indicates clock synthesizer is stable (after reset) and it is ready to set

DESCRIPTION
DIVIDE5 to 0
value 0 produces a 0.264 MHz clock and 58 produces a 2.82 MHz clock for the UART; this is
the maximum accepted by the 80C32, a smaller number is required for guaranteed
operation e.g. 15
UARTCNT
0
normal UART data input sampled by the external clock
1
select a UART data input sampled by the clock from the internal counter
EXTUART
0
use external UART clock; disables internal clock
1
switch external UART clock input from pin to this internal counter
