Serial interfaces CSI10 and CSI11 are controlled by the following five registers.
• Serial operation mode register 1n (CSIM1n)
• Serial clock selection register 1n (CSIC1n)
• Port alternate switch control register (MUXSEL)
• Port mode register x (PMx)
• Port register x (Px)
This is an 8-bit register that converts data from parallel data into serial data and vice versa.
This register can be read by an 8-bit memory manipulation instruction.
Reception is started by reading data from SIO1n if bit 6 (TRMD1n) of serial operation mode register 1n (CSIM1n) is 0.
During reception, the data is read from the serial input pin (SI1n) to SIO1n.
Reset signal generation clears this register to 00H.
Cautions 1. Do not access SIO1n when CSOT1n = 1 (during serial communication).
Remarks 1. 78K0/KA2-L (25, 32-pin products): n = 1
Remark 78K0/KA2-L (25, 32-pin products): n = 1, x = 0, 3
CSIM1n is used to select the operation mode and enable or disable operation.
CSIM1n can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Remark 78K0/KA2-L (25, 32-pin products): n = 1
2. The SSI11 pin is available only in 78K0/KA2-L (25, 32-pin products) and 78K0/KC2-L (48-pin products).
