These bits all default to a set state. Figure 14-94 shows the CAM1 register. Table 14-92 describes the fields of the CAM1 register. 29 C2TNC Carry register 2 TNCL counter carry bit 30 — Reserved 31 C2TDP Carry register 2 TDRP counter carry bit 012 3 4 5 6 7 14 15 R M1 64 M1 127 M1 255 M1 511 M1 1K M1 MAX M1 MGV 0 0 0 000 0 0 M1 RBY W Reset 1111_1110_0000_0001 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 R M1 RPK M1 RFC M1 RMC M1 RBC M1 RXC M1 RXP M1 RXU M1 RAL M1 RFL M1 RCD M1 RCS M1 RUN M1 ROV M1 RFR M1 RJB M1 RDR W Reset 1111_1111_1111_1111 Offset TSEC1:0x2_4738; TSEC2:0x2_5738 Figure 14-94.
