Oliver Schmidt ea08635ca4 Optimized CS8900A driver for speed and size. 
- Speed: The primary byte copy loops are reduzed to the bare minimum by adjusting the base pointer 'ptr' and loop register 'y' in such a way that the 'y' overflow matches the low byte of the loop size.

- Size: Factored out all repeated code into subroutines. Introduced a loop for setting the MAC address.

Additional minor changes:

- Activate frame reception as last step of initialization after CS8900A configuration.

- Properly set internal address bits used by the CS8900A.

Oliver Schmidt fb1de74dc4 The current cc65 build doesn't require this workaround anymore. 2013-06-28 00:36:33 +02:00

Oliver Schmidt 74dfff972f Do not reject frames with a length exactly equal to the uIP bufer size. 2013-01-30 23:39:01 +01:00

oliverschmidt a980f40bf6 Take in account that the C64 Retro Replay clockport needs to be activated in order to work with the RR-Net Ethernet card. 2007-12-08 21:05:48 +00:00

oliverschmidt e6e6ea415c Generic Cirrus Logic CS8900A driver for cc65 targets. The driver is intended to be loaded dynamically as relocatable module. It modifies itself to accomodate different Ethernet IO address locations: 
- C64 TFE ($DE00)
- C64 RRNet ($DE08)
- Apple2 Uther ($C0x0)
