These pins are reserved for factory testing. For normal operation they should be connected to
ground.
These pins should not be connected or terminated.
Provides the capability to supply an external cycle timer signal for the beginning of 1394 bus
cycles.
Reproduces the 8kHz cycle clock of the cycle master.
Auxiliary clock, value is SCLK/2 (usually 24.576 MHz)

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150
°
C.
