(7) UARTAn transmit data register (UAnTX)
The UAnTX register is an 8-bit register used to set transmit data.
Writing transmit data to the UAnTX register with transmission enabled (UAnCTL0.UAnTXE bit = 1) triggers
transmission. When transfer of the UAnTX register data to the UARTAn transmit shift register is complete, the
transmission enable interrupt request signal (INTUAnT) is generated.
When 7-bit data is transmitted LSB-first, the data is transferred to bits 6 to 0 of the UAnTX register. When the
data is transmitted MSB-first, it is transferred to bits 7 to 1 of the UAnTX register.
This register can be read or written in 8-bit units.
Reset sets this register to FFH.
Caution Writing the UAnTX register with transmission enabled (UAnPWR bit = 1 and UAnTXE bit = 1)
(n = 0 to 5)
UAnTX
triggers transmission. If the same value as the one immediately before is written, therefore,
the same data is transmitted twice. To write new transmit data during processing of the
preceding one, wait until the transmission enable interrupt request signal (INTUAnT) has
been generated.
Even if transmission is enabled after data is written to the UAnTX register with transmission
disabled (UAnPWR bit = 0 or UAnTXE bit = 0), transmission does not start.
After reset: FFH
