9.5
All 16 framers share a common microprocessor port and a common MCLK. There are two common software-
configurable BPCLK outputs (BPCLK[2:1]. A set of global registers includes global resets, global interrupt status,
interrupt masking, clock configuration, and the device ID register. See the global register bit map in
common JTAG controller is used for all ports.
9.5.1 General-Purpose I/O Pins
The DS26519 has 16 GPIO pins (see
to output alarm status or be used as an input. GPIO[8:1] are globally controlled as a group, and GPIO[16:9] are a
second globally controlled group. Therefore, all GPIOs in a group output the same function.

Each port has an associated framer, LIU, BERT, jitter attenuator, and transmit/receive HDLC controller. Each of the
per-port functions has its own register space.
