// NET2272 chip access option: direct or call interface
//  - Memory mapped: Fast and efficient - every chip access uses in-line 
//    'memory direct' coding
//  - Call interface: Slow (since every chip access results in a function call) 
//    but the call interface can be *extremely* helpful during early development
//    and debug.
// In either case, NCHAL is designed to be easily ported to your new hardware platform.
// The following macro determines which access method will be used...
#define NET2272_DIRECT_ACCESS TRUE  // TRUE: Use direct access (otherwise use function calls)

///////////////////////////////////////////////////////////////////////////////
// NET2272 data width access option: 8 or 16 bit
//  - EP_DATA can be configured for 16 bit access (See Data Width in LOCCTL)
//  - Non-EP_DATA registers are always 8 bit registers (see exception for REGDATA below)
//  - REGADDRPTR/REGDATA note: When Data Width is set, REGDATA is a 16 bit 
//    register for indirect accesses (via REGADDRPTR/REGDATA) to EP_DATA.
//  - PCI-RDK note: Features on the PCI-RDK and NET2272 daughterboard are applied to remap 
//    the NET2272 as a 16 bit device. The NET2272 address bits are shifted one bit (CPU A1 maps 
//    to NET2272 A0, ...). In this configuration, registers are visible at double the address 
//    given in the NET2272 chip spec. For example EP_DATA is visible at offset 0x0a instead 
//    of 0x05; further, if Data Width is set, accesses to EP_DATA are 16 bit. Other registers 
//    are always 8 bit.
//  - Split DMA can only be used when Data Width is configured in 8 bit mode!
#define NET2272_16BIT TRUE // TRUE: Use 16 bit access to NET2272 (otherwise 8 bit)
