Description

Mode Register

Fields

USART_MODE

USART Mode of Operation

0 (NORMAL): Normal mode

1 (RS485): RS485

2 (HW_HANDSHAKING): Hardware handshaking

3 (MODEM): Modem

4 (IS07816_T_0): IS07816 Protocol: T = 0

6 (IS07816_T_1): IS07816 Protocol: T = 1

8 (IRDA): IrDA

9 (LON): LON

10 (LIN_MASTER): LIN Master mode

11 (LIN_SLAVE): LIN Slave mode

14 (SPI_MASTER): SPI Master mode (CLKO must be written to 1 and USCLKS = 0, 1 or 2)

15 (SPI_SLAVE): SPI Slave mode

USCLKS

Clock Selection

0 (MCK): Peripheral clock is selected

1 (DIV): Peripheral clock divided (DIV = 8) is selected

2 (PCK): PMC programmable clock (PCK) is selected. If the SCK pin is driven (CLKO = 1), the CD field must be greater than 1.

3 (SCK): Serial clock (SCK) is selected

CHRL

Character Length

0 (_5_BIT): Character length is 5 bits

1 (_6_BIT): Character length is 6 bits

2 (_7_BIT): Character length is 7 bits

3 (_8_BIT): Character length is 8 bits

CPHA

SPI Clock Phase

CPOL

SPI Clock Polarity

CLKO

Clock Output Select

WRDBT

Wait Read Data Before Transfer
