±1/2 LSB INL; no missing codes
Programmable throughput up to 100 ksps
32 external inputs (each port I/O can be configured as an ADC input on-
the-fly)
Programmable amplifier gain: 16, 8, 4, 2, 1, 0.5
Data-dependent windowed interrupt generator
V
Programmable hysteresis
Configurable to generate interrupts or reset
On-chip emulation circuitry facilitates full-speed, non-intrusive, in-circuit
emulation
Supports breakpoints, single stepping, watchpoints, inspect/modify
memory, and registers
Superior performance to emulation systems using ICE-chips, target
pods, and sockets
Fully compliant with IEEE 1149.1 specification
