PROFIBUS Frequency Settings
AM1810 device can be configured in two ways to enable PROFIBUS. The frequencies must be set up to enable correct oversampling rate to support 12Mbaud/s on the PROFIBUS UART as well as meet the requirements for DDR memory interface. The frequency settings are listed below.

In these two modes, the operating frequencies for major peripherals are as listed in following table.

Power-on Hours for AM1810
Depending upon the configured frequency, the expectation of power-on hours changes. The Power-on Hours at 105°C and 1.2V are:

The AM1810 device datasheet lists these power on hours in Table 4-1 in section 4.3.
