C[0:15]
CONTROL DATA I/O BUS. Active high
This is the 16 bit control data I/O bus. Control register contents are
loaded into the chip or read from the chip through these pins. The
chip will only drive these pins when CE and RE are low and WE is
high.
A[0:8]
CONTROL ADDRESS BUS. Active high
These pins are used to address the control registers, phase error
RAM and the snapram memory within the chip.
WE, RE
READ/WRITE CONTROL. Active low
