2.3 Reset Circuit
2.3.1 External Reset Input
a watchdog timer reset and a system clock reset. Of these reset, the address trap reset, the watchdog timer and the
system clock reset are a malfunction reset. When the malfunction reset request is detected, reset occurs during the
maximum 24/fc[s].
ized when power is turned on. Therefore, reset may occur during maximum 24/fc[s] (1.5µs at 16.0 MHz) when
power is turned on.
The TMP86FS28DFG has four types of reset generation procedures: An external reset input, an address trap reset,
The malfunction reset circuit such as watchdog timer reset, address trap reset and system clock reset is not initial-
