The Read Display Identification Information (RDDIDIF)
command returns a 24-bit display identification
information. The identification information is valid only
5 ms after applying a hardware reset. Therefore the
RDDIDIF command should not be sent earlier than 5 ms
after a hardware reset.
The input and output data format is given in Table 9. After
the command byte 04H is sent, the read starts with one
dummy clock cycle followed by the 3 status bytes (see
Fig.47).
Table 8 Read display identification information register bits
Table 9 RDDIDIF data format for Serial mode
Table 10 RDDIDIF data format for Parallel mode
Table 11 Description of the display identification bits
Note
1. RDID3 will be programmed in OTP cells. This ID can be set to 03H by the module maker.

When less than 25 read clock cycles are sent in Serial
mode, the identification information read must be
interrupted by a hardware reset or rising edge of SCE.
The definition of the display identification bits is given in
Table 11.
