CHAPTER 3 OPERATION
3.4.9
Reading the LS-Z Interphase Pulse
If reading the LS-Z interphase pulse, set the SEL3, SEL2, SEL1 and SEL0 bits as follows, change the
SX-bus IQ area to LS-Z interphase pulse, and read at the read command ON edge.

By updating SEL3, SEL2, SEL1 and SEL0, CSEL3, CSEL2, CSEL1 and CSEL0 are updated to the
same pattern, making it possible to verify that the IQ area has been updated.
The LS-Z interphase pulse is updated when homing is performed with PA2_11 (reference signal for
shift operation) set to 1 (Encoder Z-phase) (the value is retained until homing is performed again).
