12 Cyclone PRO User Manual
CYCLONE PRO
3.8 Optional Oscillator (MON08 Only)
The Cyclone PRO provides a software configurable 9.8304MHz or 4.1952
MHz oscillator clock signal to Pin 13 of the MON08 Connector. The user may
use this clock signal to overdrive the target RC or crystal circuitry. If this signal
is not used, just leave Pin 13 of the target MON08 header unconnected.
Please note that if the target already uses an oscillator as its clock, the
Cyclone PRO will NOT be able to overdrive it. The clock should have
sufficient drive to be used with a target system even if the target system has
an RC circuit or crystal connected.
3.9 Target BDM Connector
The Cyclone PRO provides a standard 6 pin 0.100-inch pitch dual row 0.025-
inch square header for ColdFire V1, 68(S)12(X), 68HCS08, and RS08 targets.
The BDM Header uses the Motorola standard pin configuration, listed here for
reference:
PIN 1 - BKGD GND - PIN 2
PIN 3 - NC RST/Vpp - PIN 4
PIN 5 - NC Vdd - PIN 6
Please see Figure 3-7 for the physical location of the BDM connector on the
Cyclone PRO.
