NOTES:
1. RS overrides all other input signals, except for R/W
A
, EN
A
, and REQ
A
. It operates
asynchronously. RS, FR
1
, and FR
2
operates whether or not EN
A
and/or EN
B
are asserted.
At least one rising edge and one falling edge of both CK
A
and CK
B
must occur while
RS is being asserted (is LOW), with timing as defined by t
RSS
and t
RSH
.
2. Otherwise, t
RSS
, t
RSH
need not be met unless the rising edge of CK
A
and/or CK
B
occurs while that clock is enabled.
3. The parity-check even/odd selection (Control Register bit 00) is initialized to odd byte
parity at reset (HIGH). All other Control Register bits are initialized LOW. FR
1
and FR
2
do not alter the configuration, flags reflect the absence of data.
4. The AE and AF flag offsets are initialized to eight locations from the boundary at reset
controlled by RS.
