26.3.2.3.6 PRT Configuration Register 2 (PRTC2)
The communication controller accepts modifications of the register in DEFAULT_CONFIG or CONFIG
state only.
Figure 26-133 and Table 26-112 illustrate this register.

Table 26-112. PRT Configuration Register 2 (PRTC2) Field Descriptions
Bit Field Value Description
31-30 Reserved 0 Reads return 0. Writes have no effect.
29-24 TXL Fh-3Ch bit times Wakeup symbol transmit low (in bit times). These bits configure the active low phase of the
wakeup symbol. The duration must be identical in all nodes of a cluster.
23-16 TXI 2Dh-B4h bit times Wakeup symbol transmit idle (in bit times). These bits configure the number of bit times used by
the node to transmit the idle phase of the wakeup symbol. Durations must be identical in all
nodes of a cluster.
15-14 Reserved 0 Reads return 0. Writes have no effect.
13-8 RXL Ah-37h bit times Wakeup symbol receive low (in bit times). These bits configure the number of bit times used by
the node to test the duration of the low phase of the received wakeup symbol. Must be identical
in all nodes of a cluster.
7-6 Reserved 0 Reads return 0. Writes have no effect.
5-0 RXI Eh-37h bit times Wakeup symbol receive idle (in bit times). These bits configure the number of bit times used by
the node to test the duration of the idle phase of the received wakeup symbol. Must be identical
in all nodes of a cluster.
