7 / 18 page  TMC2330A PRODUCT SPECIFICATION REV. 1.1.8 10/31/00 7 RTP 11 E1 This registered input selects the current transformation mode of the device. When RTP is HIGH, the TMC2330A executes a Rectangular-To-Polar conversion. When RTP is LOW, a Polar-To-Rectangular conversion will be performed. The input and output ports are then configured to handle data in the appropriate coordinate system. This is a static input. See the Timing Diagram. ACC1,0 19, 18 H2, H1 In applications utilizing the TMC2330A to perform waveform synthesis and modulation in the Polar-To-Rectangular mode (RTP=LOW), the user determines the internal phase Accumulator structure implemented on the next clock by setting the accumulator control word ACC1,0, as shown below: ACC1,0 Configuration 00 No accumulation performed (normal operation) 01 PM accumulator path enabled 10 FM accumulator path enabled 11 (Nonsensical) logical OR of PM and FM where 0 = L0W, 1 = HIGH. See the Functional Block Diagram. The accumulator will roll over correctly when full-scale is exceeded, allowing the user to perform continuous phase accumulation through 2 π radians or 360 degrees. Note that the accumulators will also function when RTP=HIGH (Rectangular-To-Polar), which is useful when performing backward mapping from Cartesian to polar coordinates. However, most applications will require that ACC1,0 be set to 00 to avoid accumulating the Cartesian Y input data. TCXY 14 F1 The format select control sets the numeric format of the Rectangular data, whether input (RTP=HIGH) or output (RTP=LOW). This control indicates two’s complement format when TCXY=HIGH and sign-and-magnitude when LOW. This is a static input. See the Timing Diagram. OVF 105 B7 When RTP=LOW (Polar-To-Rectangular), the Overflow Flag will go HIGH on the clock that the magnitude of either of the current Cartesian coordinate outputs exceeds the maximum range. It will return LOW on the clock that the Cartesian out-put value(s) return to full-scale or less. See the Applications Discussion section. Overflow is not possible in Rectangular-To-Polar mode (RTP = HIGH). OERX, OEPY 81, 9 E13, D1 Data in the output registers are available at the outputs of the device when the respective asynchronous Output Enables are LOW. When OERX or OEPY is HIGH, the respective output port(s) is in the high impedance state. Pin Descriptions (continued) Pin Name Pin Number Description MQFP CPGA/PPGA/ MPGA |
