Description
22
INT1
OUT
Terminal not used.
23
INT0
IN
Signal to synchronized LSI with commercial power source frequency(50Hz).
This is basic timing for time processing
of LSI.
24
CNVSS
IN
Connected to VC.
25
RESET
IN
Auto clear terminal.
Signal is input to reset the LSI to the initial state when power is applied. Temporarily
set to "L" level the moment power is applied, at this time the LSI is reset. Thereafter
set at "H" level.
26
P41
IN/OUT
Memory (EEPROM) data input/output.
27
P40
OUT
Memory (EEPROM) clock out.
28
XIN
IN
Internal clock oscillation frequency input setting.
The internal clock frequency is set by inserting the ceramic filter oscillation circuit
with respect to XIN terminal.
29
XOUT
OUT
Internal clock oscillation frequency control output.
Output to control oscillation input of XOUT.
30
VSS
IN
Power source voltage: -5V.
VC voltage of power source circuit input.
31
P27
OUT
Grill (TOP) heating element driving signal.
To turn on and off the grill heating
element relay (RY3). "L" level during
grill cooking, convection cooking or
dual cooking, "H" level otherwise.
The heater relay turns on and off
within a 48 second time base in
accordance with the special program
in LSI.
32
P26
OUT
Convection heating element driving signal.
To turn on and off the relay (RY4). "L"
level during grill cooking, convection
cooking or dual cooking, "H" level
otherwise.
The heater relay turns on and off within
a 48 second time base in accordance
with the special program in LSI.
33
P25
OUT
Oven lamp and turntable motor driving signal(Square Waveform : 50Hz).
To turn on and off shut-off relay (RY1).
The square waveform voltage is
delivered to the relay (RY1) driving
circuit.
34
P24
OUT
Convection motor driving signal.
To turn on and off shut-off relay(RY7). "L"
level during convection or dual cooking "H"
level otherwise. (Relay RY7 does not turn on
at preheating mode.)
35
P23
OUT
Fan motor driving signal.
To turn on and off the fan motor relay RY6. "L"
level during cooking, or for 5 minutes after grill
cooking or for a while after convection or dual
cooking. "H" level otherwise.
