Description

One-microsecond-tick counter register

Fields

TIC_1US_CNTR

1 s tick Counter The application must program this counter so that the number of clock cycles of CSR clock is 1 s (subtract 1 from the value before programming). For example if the CSR clock is 100 MHz then this field needs to be programmed to 100 - 1 = 99 (which is 0x63). This is required to generate the 1 s events that are used to update some of the EEE related counters.
