(7) Serial status register 0n (SSR0n)
Symbol
SSR0n
SSR0n register can be read by a 16-bit memory manipulation instruction.
The lower 8 bits of SSR0n register can be set with an 8-bit memory manipulation instruction with SSR0nL.
Reset signal generation clears SSR0n register to 0000H.
Caution If data is written to the SDR0n register when BFF0n = 1, the transmit/receive data stored in
Remark
SSR0n register is a register that indicates the communication status and error occurrence status of channel n.
The errors indicated by this register are a framing error, parity error, and overrun error.
<Clear conditions>
• Communication ends.
<Set condition>
• Communication starts.
<Clear conditions>
• Transferring transmit data from the SDR0n register to the shift register ends during transmission.
• Reading receive data from the SDR0n register ends during reception.
• The ST0n bit of the ST0 register is set to 1 (communication is stopped) or the SS0n bit of the SS0 register is set to
<Set conditions>
• Transmit data is written to the SDR0n register while the TXE0n bit of the SCR0n register is set to 1 (transmission
• Receive data is stored in the SDR0n register while the RXE0n bit of the SCR0n register is set to 1 (reception or
• A reception error occurs.
