M37702M2LXXXGP, M37702S1LGP
M37702M2LXXXHP, M37702S1LHP
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 A23 – A16 to 0016, A15 – A8 to the contents of address
FFFF16, and A7 – A0 to the contents of address FFFE16.
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.
