programmed for infinite IN token retry after NAK, the SAF1761 hardware, however, does not retry the IN-token. This problem is described in the SAF1761 errata, section 18.1.1. While at it: - Add some minor chip specific initialization for RTEMS. - Add debug print for status registers in the interrupt filter.
