guarantee that no write access be executed until the previous write access takes effect (completes), by
reading the ACGPODAT.WRPEND bit prior to writing this register. If it is set for a long time, the
BITCLK signal on the AC-link is probably inactive for whatever reason.
This register specifies GPIO (slot 12) output data.
Writing a value into this register needs several BITCLK cycles to take effect. The software must
