5.3 Reset Types
A reset immediately stops the operation of the instruction being
executed, initializes certain control bits, and loads the program counter
with a user-defined reset vector address. These conditions produce a
reset:
Initial power-up (power-on reset)
A logic 0 applied to the RESET pin (external reset)
Timeout of the computer operating properly (COP) watchdog
(COP reset)
An opcode fetch from an address not in the memory map (illegal
address reset)
VDD voltage below nominal 3.5 volts (low-voltage reset)
5.3.1 Power-On Reset
A positive transition on the VDD pin generates a power-on reset. The
power-on reset is strictly for power-up conditions and cannot be used to
detect drops in power supply voltage.
A 4064 tCYC (internal clock cycle) delay after the oscillator becomes
active allows the clock generator to stabilize. If the RESET pin is at
logic 0 at the end of 4064 tCYC, the MCU remains in the reset condition
until the signal on the RESET pin goes to logic 1.
5.3.2 External Reset
A logic 0 applied to the RESET pin for one and one-half tCYC generates
an external reset. A Schmitt trigger senses the logic level at the RESET
pin.
A COP reset or an illegal address reset pulls the RESET pin low for one
internal clock cycle. A low-voltage reset pulls the RESET pin low for as
long as the low-voltage condition exists.
