17.3 Registers Controlling Serial Interface CSIA0
R01UH0008EJ0401 Rev.4.01
Jul 15, 2010
Serial interface CSIA0 is controlled by the following nine registers.
• Serial operation mode specification register 0 (CSIMA0)
• Serial status register 0 (CSIS0)
• Serial trigger register 0 (CSIT0)
• Divisor selection register 0 (BRGCA0)
• Automatic data transfer address point specification register 0 (ADTP0)
• Automatic data transfer interval specification register 0 (ADTI0)
• Automatic data transfer address count register 0 (ADTC0)
• Port mode register 14 (PM14)
• Port register 14 (P14)
(1) Serial I/O shift register 0 (SIOA0)
(1) Serial operation mode specification register 0 (CSIMA0)
This is an 8-bit register used to store transmit/receive data in 1-byte transfer mode (bit 6 (ATE0) of serial
operation mode specification register 0 (CSIMA0) = 0). Writing transmit data to SIOA0 starts the communication.
In addition, after a communication completion interrupt request (INTACSI) is output (bit 0 (TSF0) of serial status
register 0 (CSIS0) = 0), data can be received by reading data from SIOA0.
This register can be written or read by an 8-bit memory manipulation instruction. However, writing to SIOA0 is
prohibited when bit 0 (TSF0) of serial status register 0 (CSIS0) = 1.
Reset signal generation clears this register to 00H.
Cautions 1. A communication operation is started by writing to SIOA0.
This is an 8-bit register used to control the serial communication operation.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
2. Do not write data to SIOA0 while the automatic transmit/receive function is operating.
transmission is disabled (bit 3 (TXEA0) of CSIMA0 = 0), write dummy data to the SIOA0
register to start the communication operation, and then perform a receive operation.
