I

Chip Identification

Up to four MUNICH32 can be connected

to the PCM highway. These inputs define

the start address of the control section

pointer in the shared memory.

CI4 is the polarity of A31 … A22

CI3 is the polarity of A21 … A16

CI2 is the polarity of A15 … A4

CI1 is the polarity of A3

CI0 is the polarity of A2

A1, A0 are always ‘00’

I/O Test Pins

The MUNICH32 supports the JTAG

boundary scan test and the JTAG test

standards.

I

Test

If this bit is set to VDD MUNICH32 works in

a test mode.

For the functional working mode this bit

must be set to VSS.

O

Transmit Data

Serial data is sent by this PCM output port

is push-pull for active bits in the PCM

frame and tristate for inactive bits.

I

Transmit Synchronization Pulse

This signal provides the reference for the

transmit frame synchronization. It marks

the last bit in the PCM frame.

I

Transmit Clock

This clock provides the data clock for
