+/* The documentation for this chip is allegedly released */
+/* However I have not seen it, not have I managed to contact */
+/* anyone who has. HOWEVER the chip bears a striking resemblence */
+/* to the IrDA controller in the Toshiba RISC TMPR3922 chip */
+/* the documentation for this is freely available at */
+/* http://www.toshiba.com/taec/components/Generic/TMPR3922.shtml */
+/* The mapping between the registers in that document and the */
+/* Registers in the 701 oboe chip are as follows */
+
+
+/* 3922 reg 701 regs, by bit numbers */
+/* 7- 0 15- 8 24-16 31-25 */
+/* $28 0x0 0x1 */
+/* $2c SEE NOTE 1 */
+/* $30 0x6 0x7 */
+/* $34 0x8 0x9 SEE NOTE 2 */
+/* $38 0x10 0x11 */
+/* $3C 0xe SEE NOTE 3 */
+/* $40 0x12 0x13 */
+/* $44 0x14 0x15 */
+/* $48 0x16 0x17 */
+/* $4c 0x18 0x19 */
+/* $50 0x1a 0x1b */
+
+/* FIXME: could be 0x1b 0x1a here */
+
+/* $54 0x1d 0x1c */
+/* $5C 0xf SEE NOTE 4 */
+/* $130 SEE NOTE 5 */
+/* $134 SEE NOTE 6 */
+/* */
+/* NOTES: */
+/* 1. The pointer to ring is packed in most unceremoniusly */
+/* 701 Register Address bits (A9-A0 must be zero) */
+/* 0x4: A17 A16 A15 A14 A13 A12 A11 A10 */

+/* 0x2: 0 0 A31 A30 A29 A28 A27 A26 */
+/* */
+/* 2. The M$ drivers do a write 0x1 to 0x9, however the 3922 */
+/* documentation would suggest that a write of 0x1 to 0x8 */
+/* would be more appropriate. */
+/* */
+/* 3. This assignment is tenuous at best, register 0xe seems to */
+/* have bits arranged 0 0 0 R/W R/W R/W R/W R/W */
+/* if either of the lower two bits are set the chip seems to */
+/* switch off */
+/* */
+/* 4. Bits 7-4 seem to be different 4 seems just to be generic */
+/* receiver busy flag */
+/* */
+/* 5. and 6. The IER and ISR have a different bit assignment */
+/* The lower three bits of both read back as ones */
+/* ISR is register 0xc, IER is register 0xd */
+/* 7 6 5 4 3 2 1 0 */
+/* 0xc: TxDone RxDone TxUndr RxOver SipRcv 1 1 1 */
+/* 0xd: TxDone RxDone TxUndr RxOver SipRcv 1 1 1 */
+/* TxDone xmitt done (generated only if generate interrupt bit */
+/* is set in the ring) */
+/* RxDone recv completed (or other recv condition if you set it */
+/* up */
+/* TxUnder underflow in Transmit FIFO */
+/* RxOver overflow in Recv FIFO */
+/* SipRcv received serial gap (or other condition you set) */
+/* Interrupts are enabled by writing a one to the IER register */
+/* Interrupts are cleared by writting a one to the ISR register */
+/* */
+/* 6. The remaining registers: 0x6 and 0x3 appear to be */
+/* reserved parts of 16 or 32 bit registersthe remainder */
+/* 0xa 0xb 0x1e 0x1f could possibly be (by their behaviour) */
+/* the Unicast Filter register at $58. */
+/* */
+/* 7. While the core obviously expects 32 bit accesses all the */
+/* M$ drivers do 8 bit accesses, infact the Miniport ones */
+/* write and read back the byte serveral times (why?) */
