Operation at Start-up
Be sure to execute setting initialized reset (INIT) with INIT pin immediately after start-up.
Also, in order to provide the oscillation stabilization wait time for the oscillation circuit immediately after start-
up, hold the “L” level input to the INIT pin for the required stabilization wait time. (For INIT via the INIT pin,
the oscillation stabilization wait time setting is initialized to the minimum value) .
About Oscillation Input at Power On
When turning the power on, maintain clock input until the device is released from the oscillation stabilization
wait state.
Clock Control Block
Input the “L” signal to the INIT pin to assure the clock oscillation stabilization wait time.
Switch Shared Port Function
To switch between the use as a port and the use as a dedicated pin, use the port function register (PFR) .
Low Power Consumption Mode
To enter the standby mode, use the synchronous standby mode (set with the SYNCS bit as bit 8 in the TBCR :
timebase counter control register) and be sure to use the following sequence
In addition, please set I flag, ILM, and ICR to diverge to the interruption handler that is the return factor after
the standby returns.
Please do not do the following when the monitor debugger is used.
Break point setting for above instruction lines
Step execution for above instruction lines
Power-on sequence for dual-power-supply model
Notes on the power-on and power-off sequences
Power-on sequence : Vcc3B, Vcc3
→Vcc→Vcc3IO, AVRH, V0 to V3
Power-off sequence : Vcc3IO, AVRH, V0 to V3, Vcc3
→Vcc→Vcc3B, Vcc3
When VCC is turned on earlier, a potential difference between VCC and VCC3 must fall within 3.6 V.
The LCD power supply V3 must not exceed VCC in voltage. Apply V3 after turning on VCC3.
Turn on VCC3 before applying the analog power supply AVCC or an analog signal.
(LDI
#value_of_standby, R0)
: value_of_standby is write data to STCR.
(LDI
