Specification
Block Function
1. System Interface
The R61526 supports MIPI DBI TypeB (18/16/9/8 bits) and MIPI DBI TypeC (Option 1, 3). The interface
is selected by setting IM[3:0] pins.

Pins IM[3:0] are connected to IOVCC1 via a pull-up resistor. Ground to obtain a “Low” level. The above
settings can be realized. The R61526 can support MIPI DBI Type B (8 bits) by setting IM[3:0] pins to 0000
or 1111.
(a) MIPI DBI Type B (18/16/9/8 Bits)
The R61526 supports MIPI DBI TypeB (18/16/9/8 bits). It supports command method with 8-bit command
registers and 8-bit parameter registers. The LSI also has an 18-bit write/read register (WDR/RDR). The
WDR is used to temporarily store data that is automatically written to the internal frame memory in internal
operation of the chip.
The WDR is used to temporarily store the data read out from the frame memory. When reading data from
the frame memory, the R61526 first stores the data in the RDR. For this reason, invalid data is sent to the
data bus at first and valid data is sent as the R61526 reads second and subsequent data from the frame
memory.
