15.3 Register Descriptions
The SCI has the following registers. The serial mode register (SMR), serial status register (SSR),
and serial control register (SCR) are described separately for normal serial communication
interface mode and Smart Card interface mode because their bit functions partially differ.
• Receive shift register_0 (RSR_0)
• Transmit shift register_0 (TSR_0)
• Receive data register_0 (RDR_0)
• Transmit data register_0 (TDR_0)
• Serial mode register_0 (SMR_0)
• Serial control register_0 (SCR_0)
• Serial status register_0 (SSR_0)
• Smart card mode register_0 (SCMR_0)
• Bit rate register_0 (BRR_0)
