13.4 SCI Register Description
The following registers are related to the use of the
SCI peripheral.
13.4.1 SCI Configuration Registers.
SCI Control Register 1 (SCI_CR1)
Configuration Register 22 (016h) Read/Write
Reset Value: 0000 0000 (00h)
Bit 7: RXFINT SCDR_RX buffer full interrupt mask
0: interrupt disabled
1: interrupt enabled
Bit 6: OVRINT Overrun interrupt mask
0: interrupt disabled
1: interrupt enabled
Bit 5: BRKINT Break interrupt mask
0: interrupt disabled
1: interrupt enabled
Bit 4: TXEMINT SCDR_TX buffer empty interrupt
0: interrupt disabled
1: interrupt enabled
Bit 3: TXENINT TX end interrupt mask
0: interrupt disabled
1: interrupt enabled
Bit 2: PAR/T8 Parity type selection or TX 9th bit
0: parity odd if enabled, else TX 9th bit=0
1: parity even if enabled, else TX 9th bit=1
Bit 1-0: FRM Frame type selection
00: 8 bit, no parity, 1 stop bit
01: 8 bit, no parity, 2 stop bit
10: 8 bit, parity, 1 stop bit
11: 9 bit, no parity, 1 stop bit
Note: the SCI interrupts are not enabled unless the
bit 3 (MSKSCI) of the Configuration Register 0
(INT_MASK) is enabled (set to 1).
SCI Control Register 2 (SCI_CR2)
Configuration Register 23 (017h) Read/Write
Reset Value: 0000 0000 (00h)
Bit 7-4: PRESC_H Baud Rate prescaler (bit 11:8)
These bits are the higher part of the
prescaler (see
SCI_CR3 Configuration
Register) which determinates the baud rate
of the communication, according to Table
13.1 and Table 13.2, as explained in
Paragraph 13.3.
Bit 3-2: not used
Bit 1: RXSTRT Reception enable
0: RX disabled
1: RX enabled
Bit 0: TXSTRT Transmission enable
0: TX disabled
1: TX enabled
SCI Control Register 3 (SCI_CR3)
Configuration Register 43 (02Bh) Read/Write
Reset Value: 0000 0000 (00h)
Bit 7-0: PRESC_L Baud Rate prescaler (bit 7:0)
These bits are the lower part of the
prescaler (see
SCI_CR2 Configuration
Register) which determinates the baud rate
of the communication, according to Table
13.1 and Table 13.2, as explained in
Paragraph 13.3.
