Notes 1: The contents of the other registers and RAM are undefined at reset and must be initialized by software.
2: The status just after reset depends on the voltage level applied to pin MD0.
3: While Vss level voltage is applied to pin BYTE, these bits are “0”. While Vcc level voltage is applied to pin BYTE, on the other hand, these
bits are “1”.

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 104 and 105 show the microcomputer internal register’s sta-
tus just after reset, and Figure 106 shows an operation example of
the reset circuit. Apply “L” level voltage to pin RESET for a period (2
s or more) under the following conditions:
Pin Vcc’s level satisfies the recommended operating condition.
Oscillator’s operation has been stabilized.
