User Signal Pins

Data Bus D0 to D7 (Bidirectional). These pins form
the 8-bit bidirectional data bus of the microprocessor
port. They are connected to all the EVP’s.
Address A0 to A12 (Input). These inputs provide the
A12 - A0 address lines to the internal registers. They
are connected to all the EVP’s.
Chip Select (Input). These active low inputs are used
enable the microprocessor interface of each EVP.
EVP Reset (Schmitt Trigger Input). An active low
resets the device and puts the Voice Processor into a
low-power stand-by mode. When the RESET pin is
returned to logic high and a clock is applied to the
MCLK pin, the EVP will automatically execute
initialization routines, which preset all the Control
and Status Registers to their default power-up
values. Each reset pin controls a single processor. A
user can connect all of them together if required.
Receive PCM Signal Inputs (Input). Port 1 TDM data
input streams. Each Rin pin receives serial TDM data
streams at 2.048 Mb/s with 32 channels per stream.
Send PCM Signal Inputs (Input). Port 2 TDM data
input streams. Each Sin pin receives serial TDM data
streams at 2.048 Mb/s with 32 channels per stream.
