Functional Description and Application Information

4.5
To use the internal transmit (TX) and receive (RX) data FIFOs when the SPI 1 module is configured as a
master, two control signals are used for data transfer rate control: the SS signal (output) and the SPI_RDY
signal (input). The SPI1 Sample Period Control Register (PERIODREG1) and the SPI2 Sample Period
Control Register (PERIODREG2) can also be programmed to a fixed data transfer rate for either SPI 1 or
SPI 2. When the SPI 1 module is configured as a slave, the user can configure the SPI1 Control Register
(CONTROLREG1) to match the external SPI master’s timing. In this configuration, SS becomes an input
signal, and is used to latch data into or load data out to the internal data shift registers, as well as to
increment the data FIFO.

HSYN
Maximum frequency of LCDC_CLK is 48 MHz, which is controlled by Peripheral Clock Divider Register.
Maximum frequency of SCLK is HCLK / 5, otherwise LD output will be wrong.
VSYN, HSYN and SCLK can be programmed as active high or active low. In the above timing diagram, all
these 3 signals are active high.
Tpix is the pixel clock period which equals LCDC_CLK period * (PCD + 1).
Ts is the shift clock period. Ts = Tpix * (panel data bus width).
