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’
Test Pins
The MUNICH32 supports the JTAG
boundary scan test and the JTAG test
standards.
Test
If this bit is set to
a test mode.
For the functional working mode this bit
must be set to
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.
Transmit Synchronization Pulse
This signal provides the reference for the
transmit frame synchronization. It marks
the last bit in the PCM frame.
Transmit Clock
This clock provides the data clock for
