23.3.7 LCD LIDD CSn Data Read/Write Registers (LIDD_CS0_DATA and LIDD_CS1_DATA)
The LCD LIDD CS0 data read/write registers (LIDD_CSn_DATA) are accessed by the processor to
perform the data read or write operations on the CS0 and CS1 device respectively . Writing to
LIDD_CS0_DATA asserts CS0 and deasserts Address Latch Enable, which loads the DATA field of this
register into the peripheral device. Likewise, reading from this register asserts CS0 and deasserts Address
Latch Enable, which loads data from the peripheral device into the DATA field of this register. Similarly
writing to LIDD_CS1_DATA asserts CS1 and deasserts Address Latch Enable, which loads the DATA
field of this register into the peripheral device. Likewise, reading from LIDD_CS1_DATA asserts CS1 and
deasserts Address Latch Enable, which loads data from the peripheral device into the DATA field of this
register. The LIDD_CSn_DATA is shown in Figure 23-21 and described in Table 23-17.
