LCD DRIVER/CONTROLLER
The S3C72M5/C72M7/C72M9 can directly drive an up-to-1,280-dot LCD panel. The LCD function block has the
following components:
— RAM area for storing display data
— 80 segment output pins (SEG0–SEG79)
— Segment expandable circuit
— 16 common output pins (COM0–COM15)
— 5 operating power supply pins (V
LC1
–V
LC5
)
— Sixteen level LCD contrast control circuit (software)
Frame frequency, LCD clock, duty, and segment pins used for display output are controlled by bit settings in the
8-bit mode register, LMOD. You use the 4-bit LCD control register, LCON, to turn the LCD display on and off,
and to control current supplied to the dividing resistors. Segment data are output using a direct memory access
method synchronized with the LCD frame frequency (f
LCD
).
Using the main system clock, the LCD panel operates in idle mode; during stop mode, it is turned off. If a
subsystem clock is used as a clock source, the LCD panel will continue to operate during stop and idle modes.
SERIAL I/O INTERFACE
The serial I/O interface supports the transmission or reception of 8-bit serial data with an external device. The
serial interface has the following functional components:
— 8-bit mode register
— Clock selector circuit
— 8-bit buffer register
— 3-bit serial clock counter
The serial I/O circuit can be set either to transmit-and-receive or to receive-only mode. MSB-first or LSB-first
transmission is also selectable. The serial interface operates with an internal or an external clock source, or using
the clock signal generated by the 16-bit timer/counter. To modify transmission frequency, the appropriate bits in
the serial I/O mode register (SMOD) must be manipulated.
COMPARATOR
Port 4 can be used as a analog input port for a comparator. The reference voltage for the 3-channel comparator
can be supplied either internally or externally at P4.2. The comparator module has the following components:
— Comparator
— Internal reference voltage generator (4-bit resolution)
— External reference voltage source at P4.2
— Comparator mode register (CMOD)
— Comparison result register (CMPREG)
