38 / 48 page  TMC4210 DATASHEET (Rev. 1.03 / 2015-JUN-03) 38 www.trinamic.com 8 Step/Dir Drivers Step/Dir drivers contain an internal sequencer. The Step/Dir interface is a simple and universal interface for real time motion control. All additional control functions like current control have to be provided by the microcontroller directly communicating to the driver. The Step/Dir mode is enabled if the control bit en_sd (enable Step/Dir) of the IF_CONFIGURATION_4210 register is set to 1. 8.1 Timing The timing of the Step/Dir interface should be adapted to the requirements of the driver and the transmission line. The minimum pulse width may be limited. The timing of the Step/Dir interface is controlled by four LSBs named STPDIV_4210. For a given clock frequency f CLK [MHz] of the TMC4210, the length tSTEP [µs] of a step pulse is ��������������������[��������] = 16 ∗ 1 + ������������������������_4210 ����������������[������������] - For a clock frequency f CLK[MHz] of 16MHz the step pulse length can be programmed in integer multiple of 1µs by STPDIV_4210. - The STPDIV_4210 has to be set compatible to the upper step frequency f STEP = 1/tSTEP which is used. - The first step pulse after a change of direction is delayed by t DIR2STP which is equal to tSTEP to avoid setup time violations of the Step/Dir power stage. MAXIMUM STEP FREQUENCIES Generally, the maximum step pulse frequency is f STEP_MAX [MHz] = fCLK [MHz] / 32. For a clock frequency f CLK [MHz] = 16 MHz the maximum step pulse frequency fSTEP_MAX is 500kHz. For a clock frequency f CLK [MHz] = 32 MHz the maximum step pulse frequency fSTEP_MAX is 1MHz. STP DIR tSTEP tDIR2STP = tSTEP tSTEP tDIR2STP = tSTEP Figure 8.1 Step/Dir timing (en_sd = 1; step_half = 0) |
