RESET CIRCUIT
While the power source voltage satisfies the recommended operat-
ing condition, reset state is removed if pin RESET’s level returns
from the stabilized “L” level to the “H” level. As a result, program ex-
ecution starts from the reset vector address. This reset vector ad-
dress is expressed as shown below:
A23 to A16 = 0016
A15 to A8 = Contents at address FFFF16
A7 to A0 = Contents at address FFFE16
Figures 78 and 79 show the microcomputer internal register’s status
at reset, and Figure 80 shows an operation example of the reset cir-
cuit. Apply “L” level voltage to pin RESET for a period (10 s or more)
under the following conditions:
Pin Vcc’s level satisfies the recommended operating condition.
Oscillator’s operation has been stabilized.
