Copyright E 2000, TAOS Inc.
The TSL2301 is a slave device that reacts strictly to commands received from the controller. There are three
types of commands, reset commands, pixel action commands and register commands. These commands
cause the device to perform functions such as: reset, integrate, sample, etc. Each command is described in
more detail in Table 3. All commands are single-byte except for the register write command, which is two bytes.
There is a requirement for delay of 8 clocks after each command to allow for processing of the command.
