These bits define the length of the valid IB generation code programmed in the IBG[7:0] bits (b7~0, IBG,...).
00: 5-bit long in the IBG[4:0] bits (b4~0, IBG,...). (default)
01: 6-bit long in the IBG[5:0] bits (b5~0, IBG,...).
10: 7-bit long in the IBG[6:0] bits (b6~0, IBG,...).
11: 8-bit long in the IBG[7:0] bits (b7~0, IBG,...).
These bits define the length of the valid target activate IB detection code programmed in the IBA[7:0] bits (b7~0, IBDA,...).
00: 5-bit long in the IBA[4:0] bits (b4~0, IBDA,...). (default)
01: 6-bit long in the IBA[5:0] bits (b5~0, IBDA,...).
10: 7-bit long in the IBA[6:0] bits (b6~0, IBDA,...).
11: 8-bit long in the IBA[7:0] bits (b7~0, IBDA,...).
These bits define the length of the valid target deactivate IB detection code programmed in the IBD[7:0] bits (b7~0, IBDD,...).
00: 5-bit long in the IBD[4:0] bits (b4~0, IBDD,...).
01: 6-bit long in the IBD[5:0] bits (b5~0, IBDD,...). (default)
10: 7-bit long in the IBD[6:0] bits (b6~0, IBDD,...).
11: 8-bit long in the IBD[7:0] bits (b7~0, IBDD,...).
The IBG[X:0] bits define the content of the IB generation code. The ‘X’ is determined by the IBGL[1:0] bits (b5~4, IBL,...). The
IBG0 bit is the last bit to be generated. The code is generated repeatedly until the IB generation is stopped.
