CLOCK and PLL SUPPORT

MOSC

M26

I10

System clock oscillator input (3.3V LVTTL). Note that MOSC must be stable a maximum of 25ms after POSENSE

transitions from low to high.

MOSCN

N26

O10

MOSC crystal return

OCLKA

AF6

General purpose output clock A. Targeted for driving the CW motor controller. The frequency is software

programmable. Power-up default 787Khz. Note that the output frequency is not affected by non-power-up reset

operations (it will hold the last value programmed).

DUAL CONTROLLER SUPPORT

SEQ_SYNC

AB9

Sequence Sync. This signal is used in multi controller configurations only, in which case the SEQSYNC signal from

each controller is connected together with an external pull-up. This signal is either pulled high or pulled low and not

allowed to float for single controller configurations.
