19. Display Unit (DU)
19.3.5
The display unit interrupt enable register (DIER) is a register which enables interrupts to the CPU
the causes of which are internal states of the display unit (DU) reflected in DSSR. When bits are
set in this register, if bits in the same bit positions in DSSR are set, an interrupt is issued to the
CPU.
