S5U1C33001H
• If the initial connection operation fails
In this case, add a reset switch to the target system and start the system in the following sequence:
(1) Turn the target system on
(2) Hold down the reset switch on the target system and turn the S5U1C33001H on
(3) Release the reset switch to clear the reset state.
This will allow the system to operate reliably. This is because this sequence reliably reproduces the conditions in the "If
the S5U1C33001H is turned on after the target system power is turned on" item above. If it is not possible to connect,
install a reset switch on the target system. We recommend adding the reset switch at the system design stage.
• RESET/WRITE switch on the S5U1C33001H
Besides turning power on and off, the S5U1C33001H can be reset using the on-board RESET/WRITE switch.
Also the RESET/WRITE switch changes the signal output from the TARGET_RESET pin in the target system power
supply connector (see next section).
