Product data sheet
7.1.8 Repeated START: write after write
7.1.9 Power-down mode
The SC18IM700 also supports ‘write after write’ command as specified in the NXP
Semiconductors I
write command without having to issue a STOP condition between the two commands.
The host issues a write command as normal, then immediately issues a second write
command without sending a STOP (P) character after the first write command.
The SC18IM700 can be placed in a low-power mode. In this mode the internal oscillator is
stopped and SC18IM700 will no longer respond to the host messages. Enter the
Power-down mode by sending the power-down character Z (0x5A) followed by the two
defined bytes, which are 0x5A and followed by 0xA5. If the exact message is not received,
the device will not enter the power-down state.
Upon entering the power-down state, SC18IM700 places the WAKEUP pin in a HIGH
state. To have the device leave the power-down state, the WAKEUP pin should be brought
LOW. A 1 k resistor must be connected between the WAKEUP pin and V
