Clock output: outputs the SCLK clock divided by 2.
Clock output: outputs the SCLK clock divided by 4.
Master clock for telegram processing and timing control, frequency 12 to 20
MHz.
Reset, active low. Must be zero for at least 50 ns after power on.
Test, active high. Has to be tied to V
Puts outputs into high impedance state, active high: OUTZ is 1 puts all pins
into a high impedance state. The clocks are turned off and the circuit is
reset. For the in-circuit test and for turning on the powerdown mode.
NAND tree output. For the test at the semiconductor manufacturers and for
the connection test after board production. NDTRO is not set to a high
impedance state.
Ground pins.
Power supply +5 V 5%.
