TIMING INFORMATION
The TSC2008-Q1 supports SPI programming in mode CPOL = 0 and CPHA = 0. The falling edge of SCLK is
used to change the output (MISO) data, and the rising edge is used to latch the input (MOSI) data. Eight SCLKs
are required to complete the command byte cycle, and an additional eight or 16 SCLKs are required for the data
to be read, depending on the mode used.
