Read Pointer Clear Interrupt
This status flag indicates that the CLR_RD_PTR bit
in BTCR is set to 1 by the host. When the IBFIE3 bit
and CRRPIE bit are set to 1, the IBFI3 interrupt is
requested to the slave.
0: [Clearing condition]
1: [Setting condition]
Write Pointer Clear Interrupt
This status flag indicates that the CLR_WR_PTR bit
in BTCR is set to 1 by the host. When the IBFIE3 bit
and CRWPIE bit are set to 1, the IBFI3 interrupt is
requested to the slave.
0: [Clearing condition]
1: [Setting condition]
After the slave reads CRRPI = 1, writes 0 to this
bit.
When the slave detects the rising edge of
CLR_RD_PTR.
After the slave reads CRWPI = 1, writes 0 to this
bit.
When the slave detects the rising edge of
CLR_WR_PTR.
