15.2 Serial Port Control Registers
15.2.1 Control Registers for SCI0
[1]
SCI0 Transmit Control Register (ST0CON)
ST0CON is a 5-bit register that controls SCI0 transmit operations.
At reset (when the
RES
signal is input, the BRK instruction is executed, the watchdog
timer is overflown, or an operation code trap is generated), ST0CON becomes 8AH, the
SCI0 transmit operation is in UART normal mode, at 8-bit data length, 2 stop bits, and
no parity.
When changing the contents of ST0CON, do so after transmission is completed. If
ST0CON is changed before a transmission is completed, the current and future trans-
mission is not normally performed.
The 4-stage buffer mode is not provided for the transmit side.
Figure 15-3 shows the configuration of ST0CON.
<Description of Each Bit>
• ST0MD (bit 0)
This bit specifies the transmit operation mode of SCI0.
• ST0MPC (bit 2)
If SCI0 transmits in UART multiprocessor communication mode, this bit specifies
which is transmitted, data or an address. The transmit data length is 8 bits. If this bit
is "0", data is transmitted, and if "1", an address is transmitted.
• ST0STB (bit 4)
This bit specifies the stop bit of SCI0 to either 1 stop bit or 2 stop bits. If this bit is "0",
SCI0 transmits at 2 stop bits, and if "1", SCI0 transmits at 1 stop bit.
• ST0PEN (bit 5)
This bit specifies whether a parity bit is included when SCI0 transmits. If this bit is
"0", SCI0 transmits without a parity bit, and if "1", SCI0 transmits with a parity bit.
• ST0EVN (bit 6)
This bit specifies the logic of the parity bit when SCI0 transmits. If this bit is "0", an
odd parity is selected, and if "1", an even parity is selected.
