O,
LVTTL
MPOUT
Multi-purpose output pin. The output function can be selected by RTSEL of
register 0x19.
Note: When LVALID is selected, the polarity of this pin is programmable
through the POLARITY register.
80
I,
LVTTL
TMODE
This pin is used to enable the in-circuit test mode. It should be connected to
GND through a 10K ohm pull-down resistor for in-circuit test or tied to GND
directly for others. When this pin is asserted (active high), pin TEST1 and
TEST2 will determine the test to be performed.

TEST1
Test pin 1. See Test mode section for description.

TEST2
Test pin 2. See Test mode section for description.

XTI
Clock Zero pins. A 27MHz fundamental (or third harmonic) crystal can be
connected directly to these pins, or a single-ended oscillator can be
connected to XTI.

97
O,
LVTTL
CLKx1
1x clock output. The frequency of this clock is half of the crystal frequency,
i.e. 13.5Mhz when 27Mhz crystal is used.
99
O,
LVTTL
CLKx2
2x clock output. The frequency of this clock is the same as the crystal
frequency, i.e. 27Mhz when 27Mhz crystal is used.
