Kit Operation
No byte follows a # (comment) or a b (break) command.
The byte or bytes following a command type d is the delay time in milliseconds.
• The second byte in a w or r command line is the address of the configuration register. Table 7 provides
the common use address in a w and r command line.

(1)
Where the first byte is for 10 bits of resolution and the second byte is for 12 bits.
(2)
Where the two bytes reflect the different ADC bias power modes: if bit2 =1, ADC bias power ON always; and if bit2=0, it
powered down between converter.
In an r command, the byte after the address indicates the number of registers reading from; and the next
byte is ignored. If more than one register needs to be read, the next byte is the address and is followed by
two dummy bytes that are ignored.
In a w command, the two bytes after the address (see Table 7 ) are the data writing to the 16-bit TSC2004
registers. If more than one registers needs to be written, the next byte is the address and followed by two
data bytes.
For writing to TSC2004's CB1, this byte includes both address and content and thus there will be no
further byte after this address byte.
Example 1: Writing to CB1 and changing the resolution mode to 10 bit.
w 90 80
Example 2: Writing 0xA924 to CFR0 register and writing to CB0 to set ADC bias power on always.
w 90 62 A9 24
Example 3: Do the same as Example 2, but writing to CB0 to set ADC bias power OFF between
converter.
w 90 60 A9 24
Example 4: Writing the four threshold registers to set up the max=0xFF0 and min=0x00F.
