For Smart Card Interface (SMIF Bit in SCMR Set to 1): Selects GSM mode for the smart card
interface.

Note: etu: Elementary time unit (time required to transmit one bit)
Bit 6—Character Length (CHR): Selects 7-bit or 8-bits data length in asynchronous mode. In
synchronous mode, the data length is 8 bits regardless of the CHR setting,

1
Note: * When 7-bit data is selected, the MSB (bit 7) of TDR is not transmitted.
Bit 5—Parity Enable (PE): In asynchronous mode, this bit enables or disables the addition of a
parity bit to transmit data, and the checking of the parity bit in receive data. In synchronous mode,
the parity bit is neither added nor checked, regardless of the PE bit setting.
Bit 5
PE
0
1
Note: * When PE bit is set to 1, an even or odd parity bit is added to transmit data according to the
even or odd parity mode selection by the O/E bit, and the parity bit in receive data is
checked to see that it matches the even or odd mode selected by the O/E bit.
Bit 4—Parity Mode (O/E): Specifies whether even parity or odd parity is used for parity addition
and checking. The O/E bit setting is only valid when the PE bit is set to 1, enabling parity bit
addition and checking, in asynchronous mode. The O/E bit setting is ignored in synchronous
mode, or when parity addition and checking is disabled in asynchronous mode.
