GPODAT

GPIO-Out data

Reads back the value previously written to this field.

Writes data to the outgoing slot 12 bits[19:1].



Reads always ‘0’.

Figure 14.4.7 ACGPODAT Register

Writing a value into this register needs several BITCLK cycles to take effect. The software must

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.
