[Transmit Buffer/Receive Buffer Register
(TB/RB)] 001816
The transmit buffer register and the receive buffer register are lo-
cated at the same address. The transmit buffer register is
write-only and the receive buffer register is read-only. If a charac-
ter bit length is 7 bits, the MSB of data stored in the receive buffer
register is “0”.
[Serial I/O Status Register (SIOSTS)] 001916
The read-only serial I/O status register consists of seven flags
(bits 0 to 6) which indicate the operating status of the serial I/O
function and various errors.
Three of the flags (bits 4 to 6) are valid only in UART mode.
The receive buffer full flag (bit 1) is cleared to “0” when the receive
buffer is read.
If there is an error, it is detected at the same time that data is
transferred from the receive shift register to the receive buffer reg-
ister, and the receive buffer full flag is set. A write to the serial I/O
status register clears all the error flags OE, PE, FE, and SE. Writ-
ing “0” to the serial I/O enable bit (SIOE) also clears all the status
flags, including the error flags.
All bits of the serial I/O status register are initialized to “0” at reset,
but if the transmit enable bit (bit 4) of the serial I/O control register
has been set to “1”, the transmit shift register shift completion flag
(bit 2) and the transmit buffer empty flag (bit 0) become “1”.
[Serial I/O Control Register (SIOCON)] 001A16
The serial I/O control register contains eight control bits for the se-
rial I/O function.
[UART Control Register (UARTCON) ]001B16
The UART control register consists of four control bits (bits 0 to 3)
which are valid when asynchronous serial I/O is selected and set
the data format of an data transfer. One bit in this register (bit 4) is
always valid and sets the output structure of the P45/TXD pin.
[Baud Rate Generator (BRG)] 001C16
The baud rate generator determines the baud rate for serial trans-
fer.
The baud rate generator divides the frequency of the count source
by 1/(n + 1), where n is the value written to the baud rate genera-
tor.
sNotes on serial I/O
When setting the transmit enable bit to “1”, the serial I/O transmit
interrupt request bit is automatically set to “1”. When not requiring
the interrupt occurrence synchronized with the transmission
enalbed, take the following sequence.
Set the serial I/O transmit interrupt enable bit to “0” (disabled).
Set the transmit enable bit to “1”.
Set the serial I/O transmit interrupt request bit to “0” after 1 or
more instructions have been executed.
Set the serial I/O transmit interrupt enable bit to “1” (enabled).
