3.2.14 RXFH Register: Receive Flag (higher side)
Revision 0.2 (10-23-08)
RXF31-16 (bits 15 to 0)
This is a flag that indicates the receive status of pages from 16 to 31. 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. This register is effective only when page size is set to the 32-byte mode due to RAM size;
in other sizes, the readout is always “1”.
Free format receive mode
[Flag definition] 1: Receive completed/Unauthorized state
0: Receive authorized
[Clear condition] Writing “1”, or last data readout of corresponding page only in nACLR = 0
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.
