Description
BRDY Interrupt Operation Specification
0: BRDY interrupt upon transmitting or receiving of
1: BRDY interrupt upon reading of data
If this bit is set to 1, BRDY interrupts are not
generated when the buffer is set to the data writing
direction.
Double Buffer Mode
0: Single buffer
1: Double buffer
This bit is valid when PIPE1 to PIPE5 are selected.
The procedure to change this bit for a PIPE is shown
below:

Single buffer to double buffer (DBLB = 0 to DBLB
= 1)
(1) Set the PID bit to NAK for the corresponding
(2) Set the ACLRM bit in PIPEnCTR to 1.
(3) Wait for 100 ns using software.
(4) Clear the ACLRM bit to 0.
(5) Change the DBLB bit to 1.
(6) Set the response PID bit to BUF.
