When this bit is set to 1, the UART is enabled. Data transmission and reception occur for
either UART functio or SIR functio according to the setting of <SIREN>. When the UART is
disabled in the middle of transmit or receive operation, it completes current transmission or
reception before stopping.
This bit is the UART Data Transmit Ready (UxDTRn) modem status output signal. When
this bit is programmed to a 1, the output is 0.
When this bit is set to 1, the receive circuit of the UART is enabled. Data reception occurs
for either UART function or SIR function according to the setting of <SIREN>. When the
UART is disabled in the middle of receive operation, it completes current reception and
the subsequent receptions are disabled.
<TXE>
When this bit is set to 1, the transmit circuit of the UART is enabled. Data transmission
occurs for either UART function or SIR function according to the setting of <SIREN>.
When the UART is disabled in the middle of transmit operation, it completes the current
transmission before stopping.
<SIRLP> selects IrDA encoding mode. When this bit is cleared to 0, 0 bits of the IrDA
transmission data are transmitted as an active high pulse (SIROUT) with a width of
3/16
transmitted with a pulse width that is 3 times the period of the IrLPBaud16 input signal.
Setting this bit can reduce power consumption but might decrease transmission
distances.
When this bit is set to 1, the IrDA circuit is enabled. To use the UART, the <UARTEN>
must be set to 1. When the IrDA circuit is enabled, the SIR0OUT and SIR0IN pins are
enabled. The U0TXD pin remains in the marking state (set to 1). Signal transitions on
the U0RXD pin or modem status input have no effect. When IrDA circuit is disabled,
SIR0OUT remains cleared to 0 (no light pulse is generated) and the SIR0IN pin has no
effect.
