NHANCEMENTS
The OX16C950B is an enhanced, fully backward-compatible revision of the OX16C950 rev A. The chief enhancements are as
follows –
All known errata fixed
Enhanced features first offered in OX16PCI954 added – these include controls for sleep-mode sensitivity, ability to
read FCR and Good Data Status
3V operation possible with 48 pin TQFP
Enhanced isochronous clocking options (optional inversions)
Enhanced system clock selection options (use of CLKSEL as a clock input)
Readable TxRdy, RxRdy status and forcing TxRdy or RxRdy inactive
Hereafter OX16C950 rev B is simply referred to as OX16C950.
