  • This register is write-synchronized. The PATT Synchronization Busy bit in the Synchronization Busy register (SYNCBUSY.PATT) must be checked to ensure that synchronization of the Pattern Buffer (PATTBUF) register is complete.
  • This register must be written with 16-bit accesses only (no 8-bit writes)

Bits 8, 9, 10, 11 – PGVBn Pattern Generation Output Value Buffer n

These bits serves as the buffer for the PGV register. If double buffering is used, the valid content of this register is copied to the PGV register on an UPDATE condition or when the Update command is sent to the Control B Set register (CTRLBSET.CMD = UPDATE).

Bits 0, 1, 2, 3 – PGEBn Pattern Generation Output Enable Buffer n

These bits serve as the buffer of the PGE register. If double buffering is used,the valid content of this register is copied into the PGE register at an UPDATE condition or when the Update command is sent to the Control B Set register (CTRLBSET.CMD = UPDATE).
