PRODUCTION DATA
The internal GCLK frequency is configured by the Frequency Multiplier (FREQ_MUL) and is determined by the PWM resolution. The GCLK frequency can be calculated by the below equations:

where
Table 9-2 gives the values based on the system configuration and equation.
| DESIGN PARAMETER | EXAMPLE VALUE |
|---|---|
| Nsub_period | 32 |
| Nscan_line | 30 |
| TSW | 1.5 μs |
| Tblank | 0 |
| NGCLK_seg | 512 |
| GSmax | 16383 |
| fGCLK | 71.3 MHz |
Considering SCLK frequency and FREQ_MUL, the SCLK can be 27.7 MHz and FREQ_MUL can be 0010b. So the GCLK will be 83.1 MHz.
