Device 15, 29 Functions 2-5
The Device 15 and 29 Function 2-5 contain Target Address Decode, Channels Rank and
Memory Timing registers. The registers in Device 29 Functions 2 to 5 are identical to
those in Device 15 Functions 2 to 5, respectively. The Device 15 Function 2, 3, 4 and 5
registers address iMC 0 Channel 0, 1, 2 and 3, while the Device 29 Function 2, 3, 4 and
5 registers address iMC 1 Channel 0, 1, 2 and 3.

Leaky Bucket Counter High Limit (leaky_bkt_cntr_hi):
This is the upper 10-bit of the leaky bucket counter. The full counter is actually
a 53b “DCLK” counter. There is a least significant 11b of the 53b counter is not
captured in CSR. The carry “strobe” from the not-shown least significant 11b
counter will trigger this 42b counter pair to count. The 42b counter-pair is
compared with the two-hot encoding threshold specified by the
LEAKY_BUCKET_CFG_HI and LEAKY_BUCKET_CFG_LO pair. When the counter
bits specified by the LEAKY_BUCKET_CFG_HI and LEAKY_BUCKET_CFG_LO are
both set, the 53b counter is reset and the leaky bucket logic will generate a
LEAK strobe last for 1 DCLK.
