3.2.15 RXFL Register: Receive Flag (lower side)
SMSC TMC2074
RXF15-01 (bits 15 to 1)
This is flag indicates the receive status of pages 01 to 15. The definition is different depending on the
receive mode of the corresponding page. In the free format receive mode, the register becomes a writable
register. Bits from 15 to 4 are not effective when the page size is 128/256 and bits 15 to 4 are not effective
when the page size is 256 bytes (the readout is always “1”).
Free format receive mode
[Flag definition] 1: Receive completed/Unauthorized
0: Receive authorized
[Clear condition]
Remote buffer receive mode
[Flag definition] 1: Receive within a fixed time period
0: No receive within a fixed time period.
[Clear condition]
If the all-receive-inhibit bit, ECRI, in the mode register is returned from 1 to 0, all the receive flags return to
1 regardless of their receive mode.
