Section 14 Serial Communication Interface (SCI)
Bit 6—Character Length (CHR)/IrDA Clock Select 3 (ICK3): Selects 7 or 8 bits as the data
length in asynchronous mode. In synchronous mode, a fixed data length of 8 bits is used regardless
of the CHR setting,
Bit 6: CHR
Description
0
8-bit data
1
7-bit data^*
(Initial value)
Note: * When 7-bit data is selected, some bits of the transmit FIFO data register (SCFTDR) are
not transmitted according to the selection of either LSB-first or MSB-first mode in data
transmission by the TLM (bit 7) of the serial status 2 register (SC2SSR):
(1) When TLM = 0 (transmission in LSB-first mode): MSB (bit 7) is not transmitted.
(2) When TLM = 1 (transmission in MSB-first mode): LSB (bit 0) is not transmitted.
In IrDA communication mode, bit 6 is the IrDA clock select 3 (ICK3) bit, enabling appropriate
clock pulses to be generated according to its setting. See, Pulse Width Selection, in section 14.3.6,
Operation in IrDA Mode, for details.
Bit 5—Parity Enable (PE)/IrDA Clock Select 2 (ICK2): In asynchronous mode, selects whether
or not parity bit addition is performed in transmission, and parity bit checking in reception. In
synchronous mode, parity bit addition and checking is not performed, regardless of the PE bit
setting.
Bit 5: PE
Description
0
Parity bit addition and checking disabled
1
Parity bit addition and checking enabled^*
(Initial value)
Note: * When the PE bit is set to 1, the parity (even or odd) specified by the O/E bit is added to
transmit data before transmission. In reception, the parity bit is checked for the parity
(even or odd) specified by the O/E bit.
In IrDA communication mode, bit 5 is the IrDA clock select 2 (ICK2) bit, enabling appropriate
clock pulses to be generated according to its setting. See, Pulse Width Selection, in section 14.3.6,
Operation in IrDA Mode, for details.
