BASIC FUNCTION BLOCKS
The M37736EHLXXXHP has the same functions as the
M37736MHBXXXGP except for the following :
(1) The built-in ROM is PROM.
(2) The package is different.
(3) The reset circuit is different.
Refer to the section on the M37736MHBXXXGP.
RESET CIRCUIT
_____
The microcomputer is released from the reset state when the RESET
pin is returned to “H” level after holding it at “L” level with the power
source voltage at 2.7 – 5.5 V. Program execution starts at the address
formed by setting address A23 – A16 to 0016, A15 – A8 to the contents
of address FFFF16, and A7 – A0 to the contents of address FFFE16.
Figure 1 shows an example of a reset circuit. When the stabilized
clock is input from the external to the main-clock oscillation circuit,
the reset input voltage must be 0.55 V or less when the power source
voltage reaches 2.7 V. When a resonator/oscillator is connected to
the main-clock oscillation circuit, change the reset input voltage from
“L” to “H” after the main-clock oscillation is fully stabilized.
The status of the internal registers during reset is the same as the
M37736MHBXXXGP’s.

Note. In this case, stabilized clock is input from the
external to the main-clock oscillation circuit.
Perform careful evalvation at the system design
level before using.
