further parameters, which can be read, only (only used with GAP): 
180: actual current setting (Bits RD9..RD0 of TMC262 read back data, with RDSEL=10) 
182: actual microstep position (Bits RD9..RD0 of read back data, with RDSEL=00) 
206: actual load value (Bits RD9..RD0 of read back data, with RDSEL=01) 
207: state of SGTEST-Pins 
208: error bits of read back data 
8: 1=target position reached, 0=target position not reached. 
 
Parameters 0,1,2,3,4,5,8 and 181 are not directly coupled to TMC262 but are connected to the 
software ramp generator in the microcontroller.
