MC9328MX1 Reference Manual

MOTOROLA

Universal Asynchronous Receiver/Transmitters (UART) Modules

ICD

Bits 11–10

Idle Condition Detect

—Controls the number of frames 

RXD is allowed to be idle before an idle condition is 
reported.

00 = Idle for more than 4 frames
01 = Idle for more than 8 frames
10 = Idle for more than 16 frames
11 = Idle for more than 32 frames

RRDYEN

Bit 9

Receiver Ready Interrupt Enable

—Enables/Disables 

the RRDY interrupt when the RxFIFO contains data. The 
fill level in the RXFIFO at which an interrupt is generated 
is controlled by the RXTL bits. When RRDYEN is 
negated, the receiver ready interrupt is disabled.

0 = Disables the RRDY interrupt
1 = Enables the RRDY interrupt

RDMAEN

Bit 8

Receive Ready DMA Enable

—Enables/Disables the 

receive DMA request UART_RX_DMAREQ when the 
receiver has data in the RxFIFO. The fill level in the 
RxFIFO at which a DMA request is generated is 
controlled by the RXFL bits. When negated, the receive 
DMA request is disabled.

0 = Disable UART_RX_DMAREQ 

DMA request

1 = Enable UART_RX_DMAREQ 

DMA request

IREN

Bit 7

Infrared Interface Enable

—Enables/Disables the IR 

interface. See the IR interface description in Section 27.6 
for more information.

0 = Disable the IR interface
1 = Enable the IR interface

TXMPTYEN

Bit 6

Transmitter Empty Interrupt Enable

—Enables/Disables 

the transmitter FIFO empty (TXFE) interrupt. 
UART_MINT_TX. When negated, the TXFE interrupt is 
disabled

.

0 = 

Disable the transmitter FIFO 

empty interrupt

1 = 

Enable the transmitter FIFO 

empty interrupt

RTSDEN

Bit 5

RTS Delta Interrupt Enable

—Enables/Disables the 

RTSD interrupt. The current status of the UARTx_RTS 
pin is read in the RTSS bit.

0 = Disable 

RTSD interrupt

1 = Enable 

RTSD interrupt

SNDBRK

Bit 4

Send BREAK

—Forces the transmitter to send a BREAK 

character. The transmitter finishes sending the character 
in progress (if any) and sends BREAK characters until 
SNDBRK is reset. Because the transmitter samples 
SNDBRK after every bit is transmitted, it is important that 
SNDBRK is asserted high for a sufficient period of time to 
generate a valid BREAK. After the BREAK transmission 
completes, the UART transmits 2 mark bits. The user can 
continue to fill the TxFIFO and any characters remaining 
are transmitted when the BREAK is terminated. 

0 = 

Do not send a BREAK 

character

1 = 

Send a BREAK character 

(continuous 0s)

TDMAEN

Bit 3

Transmitter Ready DMA Enable

—Enables/Disables the 

transmit DMA request UART_TX_DMAREQ when the 
transmitter has one or more slots available in the TxFIFO. 
The fill level in the TxFIFO that generates the 
UART_TX_DMAREQ is controlled by the TXTL bits. 

0 = 

Disable transmit DMA request

1 = Enable 

transmit DMA request

UARTCLKEN

Bit 2

UART Clock Enable

—Enables/Disables all of the 

internal clocks of the UART module

0 = Disable 

UART clocks

1 = Enable 

UART clocks
