36.2.2 Bit Configuration Register H (CFGH)
Modify the CFGH register only in channel reset mode or channel halt mode. Set this register in channel reset mode
before making a transition to channel communication mode or channel halt mode. For setting bit timing, see
section
36.9, Initial Settings
.
TSEG1[3:0] Bits (Time Segment 1 Control)
These bits are used to specify a Tq value for the total length of the propagation time segment (PROP_SEG) and phase
buffer segment 1 (PHASE_SEG1). A value of 4 Tq to 16 Tq can be set.
TSEG2[2:0] Bits (Time Segment 2 Control)
These bits are used to specify a Tq value for the length of phase buffer segment 2 (PHASE_SEG2).
A value of 2 Tq to 8 Tq can be set. Set a value smaller than the value of the TSEG1[3:0] bits.
