C25/C25–50
In the case of the ADSP-2171/2181, the system clock is inter-
nally scaled, a 10 MHz system clock will derive a 20 MHz
CLKOUT. In the case of the TMS320C2X, the CLKOUT1
signal is derived from the system clock divided by a factor of 4,
consequently a 50 MHz TMS320C25-50 will derive a
12.5 MHz CLKOUT1 for use by the ADMC201.
Note: a pull-up resistor is required on the IRQ (Pin 18) output
from the ADMC201. The STOP (Pin 47) must be tied low if
not in use.

System Control Register (See Tables V,
VI, VII).
System Status Register (See Table VII).
These registers contain the results from
the first three analog input channels
U, V, and W. The output data format
is twos complement and, therefore, Bit 0
is always zero as the A/D converter
has 11-bit resolution.
This register contains the conversion result
of the auxiliary channels AUX0, AUX1,
AUX2 or AUX3.
PWM Master Switching Period
PWM Channel A On-Time
PWM Channel B On-Time
PWM Channel C On-Time
PWM Programmable Deadtime Value
PWM Programmable Pulse Deletion Value
These are the results of the reverse
rotation (torque and flux components).
These are the results from the forward
Clarke Transformation.

REGISTER ADDRESSING
Four address lines (A0 through A3) are used in conjunction
with the control lines (CS, WR, RD,) to select registers 0
through 15. The CS and RD control lines are active low. The
registers are given symbolic names.

Function
Enables the ADMC201 register interface
(connect via chip select logic-active low)
Places data from the internal register onto the
data bus
Loads the internal register with data on the
data bus on its positive edge
The inputs for reverse vector transforma-
tion (Clarke and Park).
These registers contain the results
of the Clarke transformation that
are the inputs to the reverse Park rotation.
VX, VY contain the results of the forward
Park rotation.
RHOP is the angle used during the
forward vector transformation. Writing to
the RHOP register causes the forward
rotation to start based on values in
RHOP, VD and VQ registers.
RHO is the angle used during the reverse
vector transformation. Writing to this
register starts the reverse rotation using
the values in the RHO, PHIP1/2/3
registers.
RHO and RHOP are unsigned ratios of
360 . For example, 45 degrees would be
45/360
Write to this register to change the
digital outputs and read from it to
determine the state of digital inputs.
This register is used to configure the
digital I/O as input or output and to
enable interrupt on change of state.
