This timing diagram shows two consecutive transmissions.
x = unknown, – = unimplemented locations read as ‘0’. Shaded cells are not used for asynchronous transmission.
Register names generically refer to both of the identically named registers for the two USART modules, where ‘x’
indicates the particular module. Bit names and Reset values are identical between modules.
