down
D Double-buffer time registers
Y
An Advanced Power supply Control (APC) that controls
the main power supply to the system, using open-drain
output, as follows:
Power turned on when:
D The RTC reaches a pre-determined date and time.
D A high to low transition occurs on the RI input sig-
nals of the UARTs.
D A ring pulse or pulse train is detected on the RING
input signal.
D A SWITCH input signal indicates a Switch On event.
Power turned off when:
D A SWITCH input signal indicates a Switch Off event.
D A Fail-safe event occurs (power-save mode detected
but the system is hung up).
D Software turns power off.
Y
Two UARTs that provide:
D Software compatibility with the PC16550A and the
PC16450
D A modifiable address that is referenced by a 16-bit
programmable register
D 13 IRQ channel options

Y
A Universal Infrared (UIR) interface on UART2 that sup-
ports TV remote circuitry and is compliant with:
D IrDA-2, including support for 4 Mbps and 1.15 Mbps
baud rates
D HP-SIR
D ASK-IR option of SHARP-IR
D DASK-IR option of SHARP-IR
D Consumer remote control (TV Remote) mode
