The On-Chip Debug Support system provides a broad range of debug and emulation
features built into the XC164N. The user software running on the XC164N can thus be
debugged within the target system environment.
The OCDS is controlled by an external debugging device via the debug interface,
consisting of the IEEE-1149-conforming JTAG port and a break interface. The debugger
controls the OCDS via a set of dedicated registers accessible via the JTAG interface.
Additionally, the OCDS system can be controlled by the CPU, e.g. by a monitor program.
An injection interface allows the execution of OCDS-generated instructions by the CPU.
Multiple breakpoints can be triggered by on-chip hardware, by software, or by an
external trigger input. Single stepping is supported as well as the injection of arbitrary
instructions and read/write access to the complete internal address space. A breakpoint
trigger can be answered with a CPU-halt, a monitor call, a data transfer, or/and the
activation of an external signal.
Tracing data can be obtained via the JTAG interface or via the external bus interface for
increased performance.
The debug interface uses a set of 6 interface signals (4 JTAG lines, 2 break lines) to
communicate with external circuitry. These interface signals are realized as alternate
functions on Port 3 pins.
Complete system emulation is supported by the New Emulation Technology (NET)
interface.

The CAPCOM units support generation and control of timing sequences on up to
32 channels with a maximum resolution of 1 system clock cycle (8 cycles in staggered
mode). The CAPCOM units are typically used to handle high speed I/O tasks such as
pulse and waveform generation, pulse width modulation (PMW), Digital to Analog (D/A)
conversion, software timing, or time recording relative to external events.
Four 16-bit timers (T0/T1, T7/T8) with reload registers provide two independent time
bases for each capture/compare register array.
The input clock for the timers is programmable to several prescaled values of the internal
system clock, or may be derived from an overflow/underflow of timer T6 in module GPT2.
This provides a wide range of variation for the timer period and resolution and allows
precise adjustments to the application specific requirements. In addition, external count
inputs for CAPCOM timers T0 and T7 allow event scheduling for the capture/compare
registers relative to external events.
Both of the two capture/compare register arrays contain 16 dual purpose
capture/compare registers, each of which may be individually allocated to either
CAPCOM timer T0 or T1 (T7 or T8, respectively), and programmed for capture or
