All of the PicoBlaze reference designs support 49 different 16- to 18-bit instructions, 8 to 32 general-purpose 8-bit registers, 256 directly and indirectly addressable ports, reset, and a maskable
048 MHz PCM input and output interfaces with selectable mu- and A-Law coding -- Selectable mu- to A-Law and A- to mu-Law conversion on a per channel or global basis -- Smart Non Linear Processing and various options for comfort noise injection -- Flexible Microprocessor Interface (SIEMENS/Intel or Motorola type) -- 256 kbit/s serial control interface -- Maskable
disabling functions: -- 2100 Hz tone with/without phase reversal detection -- 2010 Hz continuity check (SS7) -- via PCM timeslot 16-bit a, b, c, or d -- via Microprocessor Interface or Serial Interface -- Watchdog Timer -- Various clock modes for 32.
1 specification and supports 5 maskable
output clocks for secondary PCI devices.
4 kbps; seven general purpose inputs; eight general purpose outputs; TTL-compatible inputs and outputs; four transmit/receive trigger levels; a watch dog timer; clear-to-send (CTS) flow control; line signal status; receive character error flags; receive data error correction; single interrupt output; eight maskable
interrupt conditions; and internal loopback capability; and low operating and sleep mode.
interrupt can be programmed to become active when a monitored function exceeds the programmed set-point.
