CHAPTER 20 UART/SIO
20.5 Registers of UART/SIO
The registers related to UART/SIO are UART/SIO serial mode control register 1 (SMC10),
UART/SIO serial mode control register 2 (SMC20), UART/SIO serial status and data
register (SSR0), UART/SIO serial output data register (TDR0), and UART/SIO serial input
data register (RDR0).

R0/WX: Undefined bit (Read value is "0", writing has no effect on operation)
R/W: Readable/writable (Read value is the same as write value)
R(RM1), W: Readable/writable (Read value is different from write value, "1" is read by read-modify-write
instruction)
R/WX: Read only (Readable, writing has no effect on operation)
