Clocked Serial Interface 3 (CSI3)
User’s Manual U16580EE3V1UD00
<1> When the CSICAEn bit of the CSIM3n register is set to 1, operating clock supply is enabled.
<2> Specify the transfer mode by setting the CSIC3n and CSIL3n registers.
<3> Write 1 to the FPCLRn bit of the SFA3n register to clear all the CSIBUFn pointers to 0.
<4> Confirm that the SFFULn bit = 0, SFEMPn bit = 1, and SFPn3 to SFPn0 bits = 0000 in the SFA3n
register.
<5> Specify the transfer mode by using the TRMDn, DIRn, CSITn, CSWEn, and CSMDn bits of the
CSIM3n register and, at the same time, enable transmission/reception by setting both the CTXEn
and CRXEn bits to 1.
<6> Set the number of data to be transmitted/received by using the SFNn3 to SFNn0 bits of the
SFN3n register.
<7> Write transfer data to the SFDB3n register. Writing data exceeding the set value of the SFN3n
register is prohibited.
Since the chip select outputs (SCS3n0 to SCS3n3) are ineffective in the slave mode and always
output the inactive level, writing of CS data to the SFCS3n register is not necessary.
<8> Confirm that the INTC3n interrupt has occurred and the SFEMPn bit is 1. Then read the SIRB3n
register (sequentially read the receive data stored in the CSIBUFn register).
<9> Write 1 to the FPCLRn bit of the SFA3n register, and clear all the CSIBUFn pointers to 0 in
preparation for the next transfer.
<10> Confirm that the SFFULn bit = 0, SFEMPn bit = 1, and SFPn3 to SFPn0 bits = 0000 in the SFA3n
register.
<11> Disable transmission/reception by clearing the CTXEn and CRXEn bits of the CSIM3n register to
0 (end of transmission/reception).
Remarks: 1.
To execute a further transfer, repeat <6> to <10> before <11>.
