18.5.11 Extension code
R01UH0008EJ0401 Rev.4.01
Jul 15, 2010
(1) When the higher 4 bits of the receive address are either “0000” or “1111”, the extension code reception flag (EXC0)
(2) If “11110××0” is set to SVA0 register by a 10-bit address transfer and “11110××0” is transferred from the master
(3) Since the processing after the interrupt request occurs differs according to the data that follows the extension code,
is set to 1 for extension code reception and an interrupt request (INTIIC0) is issued at the falling edge of the eighth
clock. The local address stored in slave address register 0 (SVA0) is not affected.
device, the results are as follows. Note that INTIIC0 occurs at the falling edge of the eighth clock.
• Higher four bits of data match: EXC0 = 1
• Seven bits of data match:
Remark
such processing is performed by software.
If the extension code is received while a slave device is operating, then the slave device is participating in
communication even if its address does not match.
For example, after the extension code is received, if you do not wish to operate the target device as a slave device,
set bit 6 (LREL0) of the IIC control register 0 (IICC0) to 1 to set the standby mode for the next communication
operation.
Remark
Slave Address
EXC0: Bit 5 of IIC status register 0 (IICS0)
COI0: Bit 4 of IIC status register 0 (IICS0)
