Reset controller
JTAG
Common features
Watchdog timer
4. Waiting for Interrupt Mode is activated as follows:
5. Standby Mode
Standby Mode is activated when ADCCON [2] is set to '1.'
In this mode, A/D conversion operation is halted and ADCDAT0, ADCDAT1 register
contains the previous converted data.
On the module there is an Analog Devices ADM811SARTZ used. This device monitors
3.3V and has RSTIN# as debounced manual reset input and through a series resistor of
470R produces PWRGOOD as output. The voltage threshold is 2.93V. Reset output
length is typically 240ms.
The standard JTAG signals are provided at the system connector. A JTAG/Multi-ICE
connector has to be provided at the base board for debugging.
The signal DEBUGEN# (CONF0) from the base board to the module is necessary, to
be able to switch on and off a connection between the system reset and the JTAG
reset.
The pull-up resistors, belonging to the JTAG interface, are placed on the module.
The LCD controller has a dedicated DMA that supports to fetch the image data from
video buffer located in system memory. Its features also include:
The S3C2443 watchdog timer is used to resume the controller operation whenever it
is disturbed by malfunctions such as noise and system errors. It can be used as a

Dedicated interrupt functions (INT_FrSyn and INT_FiCnt)
The system memory is used as the display memory.
Supports Multiple Virtual Display Screen (Supports Hardware
Horizontal/Vertical Scrolling)
Programmable timing control for different display panels
Supports little and big-endian byte ordering, as well as WinCE data formats
After touch controller writes X-measurement data to ADCDAT0 and writes
Y-measurement data to ADCDAT1, the Touch Screen Interface generates
Interrupt source to Interrupt Controller in Auto Position Conversion Mode.
The Touch Screen Controller generates an interrupt (INT_TC) signal when
the stylus is down. Waiting for Interrupt Mode setting value is
rADCTSC=0xd3; // XP_PU, XP_Dis, XM_Dis, YP_Dis, YM_En.
After the Touch Screen Controller generates interrupt signal (INT_TC), the
user must wait for the interrupt mode to be cleared. (XY_PST sets to the
No operation Mode).
