Note: * Value is retained.
The display mode register (DSMR) is a 16-bit readable/writable register that specifies the Q2
display operation.
If the value of this register is modified during a display operation, operation will be temporarily
unstable.
DSMR is initialized as follows in a reset:
Bit YCM is initialized to 0, bits TVM1 and TVM0 to 10, and bits REF3 to REF0 to 1000.
The DOT, SCM1, and SCM0 bits retain their values.
Bits 15 to 10—Reserved: Only 0 should be written to these bits.
Bit 9—RGB-YC Conversion (YCM): Specifies YC conversion when display data is to be
output in YC mode.
Bit 9:
Y C M
Description
0
RGB-YC conversion is not performed.
(Initial value)
1
RGB-YC conversion is performed.
