SnNEG
This bit is used to choose logic of the transfer clock in the SSIO mode.
0: Positive logic (initial value)
1: Negative logic
13
SnCKT
This bit is used to choose the phase of transfer clock output in the SSIO mode.
Four types of communication are available combining the setting of SnNEG bit.
0: Clock type 0: Output with Initial value = "H" level (initial value)
1: Clock type 1: Output with Initial value = "L" level
12 to 8
SnCK4 to
SnCK0
These bits are used to choose the transfer clock of SSIO.
When an internal clock is chosen for the transfer clock, the SSIO performs the master mode.
When an external clock is chosen, it performs the slave mode.
In the slave mode, input the external clock with 1/8 frequency of the system clock or lower.
