Seven-bit address input for addressing registers
within the chip. Addresses are loaded when AS~
is low.
Used to synchronize PLCP, and drive ONESECO.
1 Hz input used to latch line status every one
second.
If asserted, this pin stops the cell receiver.
Connect to Vcc for normal operation.
Connect to ground for normal operation.
Active-high pulse on power-up for at least
100 ns. This pin resets the internal state
machines. It does not affect the contents of the
registers, except bit 9 of register 0x02.
One-second count derived from count of 8 kHz
input.
Eleven pins are provided for supply voltage.
Twelve pins are provided for ground.
