UART
The baseband chipset houses three UARTs. The UARTs provide full duplex serial communication channels between
baseband chipset and external devices. The UART has M16C450 and M16550A modes of operation, which are compatible
with a range of standard software drivers.
In MASS2
, UART1(URXD1, UTXD1) is used for Factory Programming and UART3(URXD3, UTXD3) is used for Blue
Tooth Programming.

RX data Timeout Interrupt :
When virtual FIFO mode is disabled, RX data Timeout Interrupt is generated if all of the following apply :
1.
FIFO contains at least on character.
2.
The most recent character was received longer than four character periods ago(including all start, parity and stop bit)
3.
The most recent CPU read of the FIFO was longer than four character periods ago.
When virtual FIFO mode is enabled, RX Data timeout Interrupt is generated if all of the following apply:
1.
FIFO is empty.
2.
The most recent character was received longer than four character periods ago(including all start, parity and stop bit)
3.
The most recent CPU read of the FIFO was longer than four character periods ago
IrDA : Available
MASS2 uses the HSDL-3208 IrDA Module. The HSDL-3208 is an ultra-small low cost infrared transceiver module that
provides the interface between logic and infrared(IR) signals for through air, serial, half duplex IR data link. The Module is
