78 * - The October 1999 errata (278260-007) says its bit 13, 1 to enable.
79 * - The Feb 2001 errata (278260-010) says that the previous errata
80 * (278260-009) is wrong, and its bit actually 12, fixed in spec
82 * - The SA1111 manual (278242) says bit 12, but 0 to enable.
83 * - Reality is bit 13, 1 to enable.
