void aI2C_Write4(

char addr, char reg, char a, char b, char c, char d);

Parameters:

addr	-	The address of the I2C device.
reg	-	The register where the write operation will begin.
a	-	The first data byte to be written.
b	-	The second data byte to be written.
c	-	The third data byte to be written.
d	-	The fourth data byte to be written.

Return Value:

This routine does not return a value.

Description:

This routine writes 4 bytes to an I2C device.  The device must use single-byte register addresses.  The IIC baud rate may need to be lowered to achieve reliable communication with the I2C device.  See the cmdVAL_SET or aPortIICBaud documentation for details.

Example:

aI2C_Write4((unsigned char)0xC0, 5, 1, 2, 3, 4);


This would write the bytes 1, 2, 3, 4 starting at register 5 in an I2C device with an address of 0xC0 (192).
