Buzzer

The buzzer is used for alarm by the application. It is connected to MCU pin P01/PCLBUZ1
5.4.6

Description of Push Button

The push button is connected MCU pin P137 / INTP0 via R3, and used as "Reset" function. The Interrupt function can
be found in the project file "r_cg_intc_user.c"

Button Status
SW1 Un-pressed
Pressed
UM-YDETECT-IT-RL78 V1.30
Function
Power supply of the MCU and others components [MCU, Alarm/buzzer, AVDD
via L1, U1 Vin (optional), pull up resistors]: power from battery or power from
E1 via CN01-pin 5, CN02-pin 4
Caution: Battery should never be installed when using E1 power supply or
external power supply via CN02/CN01
Current measurement of the MCU and others components [MCU,
Alarm/buzzer, L1and AVDD, U2 Vin (optional), pull up resistors] by connection
of the ampere meter
Power supply of some components [R67/68, J6] on motion detector board
Current measurement of some components [R67/R68, J6] by connection of the
ampere meter
Usage of Rl78/I1D comparators
(motion detector and glass break detector board)
Comparators are not used, IVREF0 & IVREF1 are not used
(CO detector and smoke detector board)
Enable IR LED transmission (Provide CON2/J11 with VDD_Sensor)
Disable IR LED transmission.
Enable IR LED photodiode reception (Normal Operation)
Disable IR LED photodiode transmission, could be used by test mode (with SW
change)
Function
Could be used when J3 is closed (please check schematics for more
details).
Could be used when J3 is closed (please check schematics for more
details).
Function
INTP0 is high – no operation
INTP0 goes Low – interrupt function is executed which defeats alarm
(software depending)
