NOTES:
C1 and C2 should be based on manufacturer’s specification.
X1 and X2 parasitic capacitance IS 1-2pF AND 3-5pF, respectively.
GAIN:
PHASE: at 4MHz 272 to 276 ; at 8MHz 272 to 276
The above figures for 5V operation. Operation at 3V is to be determined.
Octal UART for 3.3 V and 5 V supply voltage
NOTE: CEN must not be active during an IACKN cycle. If CEN is active, IACKN will be ignored
C1 and C2 should be chosen according to the
crystal manufacturer’s specification.
C1 and C2 values will include any parasitic
capacitance of the wiring.

and a normal read or write will be executed according to W_RN. In the synchronous
mode, extended IACKN signal will start another IACKN. (This may not be desired, but
is allowed.)
