Address: F0100H, F0101H (SSR00) to F0106H, F0107H (SSR03),
(6) Serial status register mn (SSRmn)
SSRmn
Symbol
SSRmn can be read by a 16-bit memory manipulation instruction.
The lower 8 bits of SSRmn can be set with an 8-bit memory manipulation instruction with SSRmnL.
Reset signal generation clears this register to 0000H.
Remark
SSRmn 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.
F0144H, F0145H (SSR12), F0146H, F0147H (SSR13)
Because this flag is an updating flag, it is automatically cleared when the communication operation is completed.
This flag is cleared also when the STmn/SSmn bit is set to 1.
This is an updating flag. It is automatically cleared when transfer from the SDRmn register to the shift register is
completed. During reception, it is automatically cleared when data has been read from the SDRmn register. This
flag is cleared also when the STmn/SSmn bit is set to 1.
This flag is automatically set if transmit data is written to the SDRmn register when the TXEmn bit of the SCRmn
register = 1 (transmission or reception mode in each communication mode). It is automatically set if receive data is
stored in the SDRmn register when the RXEmn bit of the SCRmn register = 1 (transmission or reception mode in
each communication mode). It is also set in case of a reception error.
If data is written to the SDRmn register when BFFmn = 1, the transmit/receive data stored in the register is
discarded and an overrun error (OVFmn = 1) is detected.
