SPY_No_SubframeIndication (A0h)

If the ST7570 is configured to operate in PHY mode and as Monitor (refer to Section 3.4.1),

and it is mains synchronized, this command is sent to indicate that no valid preamble+SSD

sequence has been detected during the current time-slot.

Available in PHY mode only.

5.3.18

SPY_SubframeIndication (B0h)

If the ST7570 is configured to operate in PHY mode and as Monitor (Section 3.4.1), and is

mains synchronized, this command is sent to indicate the reception of a valid physical

subframe.

This command replaces the CMD_DataIndication used for ‘Client’ and ‘Server’ operating

modes.

Available in PHY mode only.
