#define device_id          C8051F340

// If set, locates the transmit buffer in the USB FIFO space of the C8051F34x.
#define  c8051f340_usb_fifo   0

// Sets the number of sockets that can be used. The value must be between
// 1 and 127. Each socket uses about 46 bytes of RAM.
#define num_sockets			3

// Sets the size of the buffer used for transmission
#define xmit_buff_size		560

// Sets the size of the buffer used for reception
#define recv_buff_size		840

// Number of system ticks to wait for a packet
#define socket_wait_ticks	100

// Sets the time to live field in the IP packet
#define ip_time_to_live     64

// Sets the time to live field in an IP packet for multicast packets
#define multicast_ttl		1

// Timer 0  reload values such that Timer 0 overflows in 10ms.
// This defines a system tick.
#define tl0_flash			   0xEF
#define th0_flash			   0xD8

// Number of system ticks to wait for an ethernet packet
#define ether_wait_ticks	5

// Number of system ticks to keep entries in the ARP cache
#define arp_keep_ticks		6000

// Number of times an ARP packet is re-transmitted
#define arp_resend_trys		6

// Number of system ticks to wait for an ARP packet
#define arp_wait_ticks		600

// Number of entries in the ARP cache
#define arp_cache_size		4

// When set to 1, the ARP cache is updated after every valid packet is received.
// The ARP cache is always updated on PING requests
#define arp_auto_update		0

// Number of times a DHCP packet is transmitted before terminating the connection
#define dhcp_resend_trys	3

// Lease time, in seconds, to ask for. Default is 36000 (10hrs).
#define dhcp_default_lease_time	36000

// Buffer used to process HTTP includes. Should be the same size as TCP window
#define http_buffer_len		256

// Size of buffer used to hold the URI sent by an HTTP GET, POST, or HEAD request.
#define uri_buffer_len     52

// Size of the buffer used to hold the body sent by an HTTP POST request.
#define body_buffer_len    52

// If PING is enabled the value is the size of the data from a PING request that
// can be stored. 9 bytes are added to the value to store part of the PING request
// header also. If the PING request contains more data than the specified value the
// packet will be discarded and no reply sent. The default value is 32.
#define ping_buff_size		32

// This value is both the amount of data you are willing to accept from the remote
// connection and the amount of data you are sending in a single packet. This value must
// be greater than 0 and less than or equal to 1460. A larger value will yield better
// throughput but require larger buffers. Note: The TCP/IP Stack uses a fixed window when
// receiving, not a sliding window as specified in RFC 793. If using PPP, the
// RECV_BUFF_SIZE and XMIT_BUFF_SIZE should be at least double the TCP
// window to allow for escaped characters. If using ethernet the RECV_BUFF_SIZE and
// XMIT_BUFF_SIZE should be at least TCP_WINDOW + 58.
#define tcp_window		256

// Number of system ticks to wait before retransmitting a TCP packet
#define tcp_resend_ticks	100

// Number of times a TCP packet is transmitted before aborting the connection
#define tcp_resend_trys		12

// The number of entries in the directory table in the virtual file system. Can be 1 to 255.

// This value is the number of entries in the post-function table in the virtual file system.
// The value can be 1 to 255.
#define num_post_funcs		1

// The C8051F340 has 4K of on-chip XRAM. Off-chip access begins at 0x1000.
