3.7.10.7 IEM Control SFRs (FREQ_CPU, R/W, Address = 0xE010_3060)
FREQ_CPU
Reserved
FREQ_CPU
The register is related to IECCFGFREQCPU[23:0] of IEM_IEC input port. FREQ_CPU[23:0] is the maximum
processor of frequency in KHz, and gives the clock frequency of the processor in KHz. Examples values are
shown in the following table.
FREQ_CPU[23:0]
0x00_4E20
0x03_A980
0x00_03E8

FREQ_DPM
Reserved
FREQ_DPM
The register is related to IECCFGFREQDPM[23:0] of IEM_IEC input port. FREQ_DPM[23:0] is the DPM
frequency in KHz, and gives the rate that the DPM is accumulating in KHz. Examples values are shown in the
following table.
FREQ_DPM[23:0]
0x00_4E20
