/* 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 */
/* $134 SEE NOTE 6 */
/* */
/* NOTES: */
/* 1. The pointer to ring is packed in most unceremoniusly */
/* 701 Register Address bits (A9-A0 must be zero) */
/* 0x4: A17 A16 A15 A14 A13 A12 A11 A10 */
/* 0x5: A25 A24 A23 A22 A21 A20 A19 A18 */
/* 0x2: 0 0 A31 A30 A29 A28 A27 A26 */
/* */
/* 2. The M$ 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 writing 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?) */
