FIGURE 13. RESET TIMING (CLK RUNNING WITH F/C LOW-OSC MODE)
(CLK RUNNING-OR STOPPED WITH F/C HIGH EFI MODE)
FIGURE 14. RESET TIMING (OSCILLATOR STOPPED, F/C LOW)
NOTE: CLK, CLK50, PCLK Remain in the High State until RES goes high and 8192 valid oscillator cycles have been registered by the 82C85
internal counter (TOST time period). After RES goes high and CLK, CLK50, PCLK become active, the RESET output will remain high
for minimum of 16 CLK cycles (TRST).
