Function
Interrupt Request
INT serves as general interrupt request which
may include all interrupt sources. These
interrupt sources can be masked via registers
IMR0 … 4. Interrupt status is reported via
registers GIS (Global Interrupt Status) and
ISR0 … 3.
Output characteristics (push-pull active low/
high, open drain) are determined by
programming the IPC register.
Interface Mode
The level at this pin defines the bus interface
mode:
A low signal on this input selects the INTEL
interface mode. A high signal on this input
selects the Motorola interface mode.
Positive Power Supply for the analog receiver.
Line Receiver 1
Analog Input from the external transformer.
Selected if LIM1.DRS = 0.
Receive Data Input Positive
Digital input for received dual rail PCM(+) route
signal which will be latched with the internal
generated Receive Route Clock. An internal
DPLL will extract the Receive Route Clock from
the incoming data pulse. The Duty cycle of the
receiving signal has to be closely to 50 %.
The Dual Rail mode is selected if LIM1.DRS = 1
and FMR0.RC1 = 1. Input sense is selected by
bit RC0.RDIS (after Reset: active low).
Receive Optical Interface Data
Unipolar data received from fibre optical
interface with 2048 kbit/s. Latching of data is
done with the falling edge of RCLKI. Input
sense is selected by bit RC0.RDIS.
The Single Rail mode is selected if
LIM1.DRS = 1 and FMR0.RC1 = 0.
