Section 16 Serial Communication Interface with FIFO (SCIF)
Bit 6—Character Length (CHR): Selects 7 or 8 bits as the asynchronous mode data length.
Bit 6: CHR
Description
0
8-bit data
(Initial value)
1
7-bit data*
Note: * When 7-bit data is selected, the MSB (bit 7) of SCFTDR2 is not transmitted.
Bit 5—Parity Enable (PE): Selects whether or not parity bit addition is performed in
transmission, and parity bit checking in reception.
Bit 5: PE
Description
0
Parity bit addition and checking disabled
(Initial value)
1
Parity bit addition and checking enabled*
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.
Bit 4—Parity Mode (O/E): Selects either even or odd parity for use in 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. The O/E bit setting is invalid when parity addition and checking is disabled.
Bit 4: O/E
Description
0
Even parity^*1
(Initial value)
1
Odd parity^*2
Notes: 1. When even parity is set, parity bit addition is performed in transmission so that the total
number of 1-bits in the transmit character plus the parity bit is even. In reception, a
check is performed to see if the total number of 1-bits in the receive character plus the
parity bit is even.
2. When odd parity is set, parity bit addition is performed in transmission so that the total
number of 1-bits in the transmit character plus the parity bit is odd. In reception, a check
is performed to see if the total number of 1-bits in the receive character plus the parity
bit is odd.
