[Burst access mode]

By maintaining SCEN as L, Burst access mode will be active. By setting SCEN line to “H”, exiting from the burst access

mode. During burst access mode, address will be automatically incremented.

When SCEN become H before Clock for D0 is input, data transaction will be aborted.

[Note]

If destination is [WR_TX_FIFO:B0 0x7E] or [RD_RX_FIFO:B0 0x7F] register, address will not be incremented. And

continuous FIFO access is possible.

[Note]

When using IEEE802.15.4d mode, it is need to read “Length+1” bytes of data from RX FIFO for switching the FIFO banks

correctly. (The last byte is invalid data.)

●AFC function

ML7396 family supports AFC function during RX operation. Frequency deviation (max +/- 20ppm) between remote device

and local device can be compensated by this function. Using this function, stable RX sensitivity and interference blocking

performance can be achieved.

This function can be activated by setting AFC_EN ([AFC_CNTRL:B0 0x34(0)]) =0b1

This is not supported for optional data rate. (other than 50/100/150/200/400kbps) When using optional data rate, AFC_EN

should be set to 0b0.
