4.9 Calculating Accelerator(CALC)
The calculating accelerator (CALC) can perform calculation acceleration of square root and division.
The features are described as follows:

Support up to 32-bit unsigned square root operation
 Support division of up to 32-bit signed and unsigned numbers

Support the use of DMA write data to perform calculating operations
4.10 Advanced Timer(ADTIM)
The advanced-control timer (ADTIM) consists of a 16-bit auto-load counter driven by a programmable
Prescaler. It may be used for a variety of purposes, including measuring the pulse widths of input signals
(input capture), or generating output waveforms (output compare, PWM, complementary PWM with
