MC2300 Technical Specifications
Description
This signal provides the clock pulse for the CP chip. Its frequency is half
that of MasterClkIn (pin 89), or 20 MHz nominal. It is connected directly
to the CP chip I/Oclk signal (pin 58).
These two signals determine the host communications mode, as follows:
HostMode1 HostMode0
0
0
1
1
These signals transmit data between the host and the Motion Processor
through the parallel port. Transmission is mediated by the control signals
~HostSlct, ~HostWrite, ~HostRead and HostCmd.
In 16 bit mode all 16 bits are used (HostData0-15). In 8 bit mode only the
low-order 8 bits of data are used (HostData0-7). The HostMode0 and
HostMode1 signals select the communication mode this port operates in.
These signals transmit data between the I/O chip and pins Data0-15 of
the CP chip, via the Motion Processor data bus.
These pins provide the Pulse Width Modulated signals for each phase to
the motor.
In PWM 50/50 output mode the sign (direction) is encoded within each
signal. Refer to the User’s Guide for more information.
The PWM resolution is 10 bits at a frequency of 20.0 KHz.
For MC2340 all pins are valid. For MC2320 only PWMMag1A-C and
PWMMag2A-C are valid. For MC2310 only PWMMag1A-C is valid.
Invalid or unused pins may be left unconnected.
