o This address header is used to select an I2C address of SC18IS602/603 on
o SC18IS602 uses an internal clock so it does not require an external clock.
o SC18IS603 requires an external clock so an oscillator should be installed
with I2C bus master capability interfacing to SC18IS602/603 (I2C-to-SPI
bus controller) Bridge. The signals need to be attached to the I2C bus are
VCC, SDA, SCL, INT, RST, and GND.
the I2C host. If an interrupt method is used, the INT signal should be
connected to the input interrupt of the I2C host for servicing the interrupt
when occurred.
I2C host. The host can reset the SC18IS602/603 and upon reset, the
SC18IS602/603 registers will be initialized with the default values.
be attached to the SPI bus are VCC, MISO, MOSI, SCLK, GND. The four
chip selects (SSO, SS1, SS2, SS3) need to be connected to the SPI slave
devices so one chip select is for one SPI slave device. Thus, up to four SPI
slave devices can be connected to the SC18IS602/603
can be used for general-purpose input/output (GPIO). Peripherals such as
LEDs and switches can be connected to the GPIO. The programmable
GPIO can drive LEDs as output from the SC18IS602/603 and detect
switches as input to the SC18IS602/603.
the I2C-bus. The SC18IS602/603 has three bit addresses (A0, A1, A2) so
8 different addresses can be selected and the host can identify the
SC18IS602/603 with its I2C address.
An oscillator installed on the OSC1 location should be removed.
