Table 27.
Any subsequent data bytes in this case will be ignored.
Table 28.
Table 29.
On power application, the normal operation mode and address increment mode is set with
the default display memory address set to 0x10 (start of display memory address location).
Refer to the display memory section.
In the auto increment address mode, the address command is sent once followed by the
data bytes.
Alternatively, the data command can be sent followed by the data bytes. In this case, when
new display data is to be written, the last value of the address will be used and then
incremented. Upon reaching the last display memory address, the address jumps to 0x10,
as it represents the first address location of the display memory.

Read configuration byte values (see section on configuration bytes)
Read LED display memory
Read RTC memory. Address command must be issued prior to reading.
Read Key (following 2 bytes will contain key data)
Read GPIO register (following 1 byte will contain the GPIO data with
MSB7: GPIO1 data and MSB6: GPIO0 data). This is the input monitor for
GPIO[1:0] for reading purpose. When b7 of subsequent byte is low, it
means that GPIO1 input is low and when it is high, it means that GPIO1
input is high. When b6 of subsequent byte is low, it means that GPIO0
input is low and when it is high, it means that GPIO0 input is high.
Read RC data (following four bytes are the address + command bytes from
RC)
Read Interrupt status register (refer to the Interrupt Flag section for
detailed description)
