The INTERLEAVE command sets the phase delay
between the external SYNC (IN or OUT) and the
internal PMW oscillator.

The (37h) INTERLEAVE
command is used to arrange multiple devices
sharing a common SYNC signal in time. The phase
delay added to each device is equal to 360° /
Number in Group × Order. To prevent misaligning
the phases of a multi-phase stack, (37h) INTERLEAVE
is read only when the TPSM8D6B24 is configured as part of a
multi-phase stack. The Read/Write status of the
(37h) INTERLEAVE
command is set based on the state of the (ECh) MFR_SPECIFIC_28 (STACK_CONFIG)
command at power-on and is not updated if (ECh) MFR_SPECIFIC_28 (STACK_CONFIG)
is later changed. If (37h) INTERLEAVE
is used to program the phase position of a
standalone device, the TPSM8D6B24 must be configured as a
standalone device at power-on to ensure write
capability of the (37h) INTERLEAVE
command.
