Output Drive Enable (5 V Tolerant Input). When this pin is low, LSTo0-15,
BSTio0-31, C1M5o, C32/64o, ST_CKo0, ST_CKo1, ST_FPo0 and
ST_FPo1 outputs are all in high-impedance state. When ODE is high all of
the aforementioned pins are active.
Master Clock (5 V Tolerant Input). This pin accepts a 20.000 MHz clock.
Clock A (5 V Tolerant I/O). This is an 8.192 MHz clock with 50% duty cycle.
