function time_period_seconds = calcWatchdogTimePeriod(oscclkinMHz, dividers) %CALCWATCHDOGTIMEPERIOD Calculates the time required to overflow the %wathdog timer. The formula to calculate is % Time_period = OSCCLK/512/DIVSEL % where DIVSEL = 2^(0, 1, 2, 3, 4, 5, 6) % Copyright 2012 Mathworks, Inc OSCCLK = oscclkinMHz * 1e6; % MHz to Hz watchdog_freq = OSCCLK; for i = 1:numel(dividers) watchdog_freq = watchdog_freq/dividers(i); end % The watchdog counter considered is 8-bit counter. Hence the value 2^8 = % 256 is considered to calculate total time required to overflow the % watchdog counter. time_period_seconds = 256/watchdog_freq;
