CSIGnCTL1 - CSIG Control Register 1
This register specifies the interrupt timing and the interrupt delay mode. It
enables/disables extended data length control, data consistency check, loop-
back mode, and handshake function.
Access
This register can be read/written in 32-bit units.
Address

CSIGnCTL1 Register Contents (1/2)
Bit Position
Bit Name
Function
17
CSIGnCKR
Selects the phase of the CSIGnTSCK clock signal.
0: Default level of CSIGnTSCK is high
1: Default level of CSIGnTSCK is low
For the setting example, refer to the CSIGnDAP bit in Table 21-15,
CSIGnCFG0 Register Contents.
16
CSIGnSLIT
Selects the timing of interrupt CSIGnTIC:
0: Normal interrupt timing (interrupt is generated after the transfer)
1: Interrupt is generated when CSIGnTX0W or CSIGnTX0H is free for further
data.
For details, refer to Section 21.3.8 (1), CSIGnTIC (Communication Interrupt).
7
CSIGnEDLE
Enables/disables extended data length (EDL) mode:
0: Extended data length mode disabled
1: Extended data length mode enabled
For details, refer to Section 21.3.5 (2), Data Length Greater than 16 Bits..
5
CSIGnDCS
Enables/disables data consistency check:
0: Data consistency check disabled
1: Data consistency check enabled
For details, refer to Section 21.3.11 (1), Data Consistency Check.
