Operation and Timing
Before operation, the TMC2255 must be initalized, i.e.
loaded with coefficients and set to the desired operating
mode, data format, and rounding precision. The chip is pro-
grammed via ports D and E, which double as data input ports
in 5x5 mode.
Initialization
Chip Select
This control is accessed through bit 7 of port D. When CLE
is LOW, D

must be LOW to allow the coefficient/control
information to be updated. If D
LOW, the device will not allow the coefficient or control
information to be updated, and device execution will begin
or continue as commanded on the previous LOW-to-HIGH
transition of CLE. Holding D
