Indirect Register 3. IPGT: Back-to-Back Inter-Packet Gap Register
Indirect Register 4. IPGR: Non-Back-to-Back Inter-Packet Gap Register
Bits 15–7:Reserved. Read = 000000000b; Must write 000000000b.
Bits 6–0: IPGT: Back-to-Back Inter-Packet Gap Register
Sets the minimum delay between the end of any transmitted packet and the start of a new packet.
In Full-Duplex mode, the register value should be set to the desired number of time units (each time
unit is 0.46 s) minus 3. The recommended setting is 0x15 (21d), which yields 9.6 s.
In Half-Duplex mode, the register value should be set to the desired number of time units (each time
unit is 0.46 s) minus 6. The recommended setting is 0x12 (18d), which yields 9.6 s.

Bits 14–8:IPGR1: Non-Back-to-Back Inter-Packet Gap Part 1
Sets the optional carrier sense window referenced in IEEE 802.3 Section 4.2.3.2.1. The range of
values for this bit field are 0x00 to IPGR2. The recommended value is 0x0C.
Bit 7:
Reserved. Read = 0b; Must write 0b.
Bits 6–0: IPGR2: Non-Back-to-Back Inter-Packet Gap Part 2
Sets the Non-Back-to-Back Inter-Packet Gap. The recommended value is 0x12, which represents a
minimum inter-packet gap of 9.6 s.
