Preliminary Specification
This is a preliminary specification and is subject to change.
23. Serial Interface UARTi (i = 0 to 2, 5 to 7)
23.2 Registers
Table 23.3 and Table 23.4 list registers associated with UART0 to UART2 and UART5 to UART7.
Set the OCOSEL0 or OCOSEL1 bit in the UCLKSEL0 register before setting other registers associated
with UART0 to UART2 and UART5 to UART7. After changing the OCOSEL0 or OCOSEL1 bit, set other
registers associated with UART0 to UART2 and UART5 to UART7 again.
Refer to “Registers Used and Settings” in each mode for the settings of registers and bits.
