SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
BASIC FUNCTION BLOCKS
The M37702M2LXXXGP has the same functions as the
M37702M2BXXXFP except for the reset circuit.
Refer to the section on the M37702M2BXXXFP.
RESET CIRCUIT
Reset occurs when the RESET pin is returned to “H” level after
holding it at “L” level when the power voltage is at 2.7 – 5.5 V. Pro-
gram execution starts at the address formed by setting the
address pins A
23
– A
16
to 00
16
, A
15
– A
8
to the contents of address
FFFF
16
, and A
7
– A
0
to the contents of address FFFE
16
.
Fig. 1 Microcomputer internal status during reset
Figure 1 shows the status of the internal registers when a reset
occurs.
Figure 2 shows an example of a reset circuit. The reset input volt-
age must be held 0.55 V or lower when the power voltage reaches
2.7 V.
