INTERFACES
multiframe. When ITMFH4 is set low, ITMF marks the third byte after J1.
ITMFH4 is ignored if ITMF is disabled by setting the ITMFEN bit low.
IOP:
The IOP bit controls the expected parity on the corresponding incoming parity
signal IDP. When IOP is set high, the parity of the parity signal set, together
with IDP is expected to be odd. When IOP is set low, the expected parity is
even. Membership of the parity signal set always includes ID[7:0], and may
include input signals IC1J1 and IPL as controlled by the INCIC1J1 and
INCIPL bits, respectively.
INCIC1J1:
The INCIC1J1 bit controls whether the corresponding IC1J1 input signal
participates in the incoming parity calculations. When INCIC1J1 is set high,
the parity signal set includes the IC1J1 input. When INCIC1J1 is set low,
parity is calculated without regard to the state of IC1J1. Selection of odd or
even parity is controlled by the IOP bit.
INCIPL:
The INCIPL bit controls whether the corresponding IPL input signal
participates in the incoming parity calculations. When INCIPL is set high, the
parity signal set includes the IPL input. When INCIPL is set low, parity is
calculated without regard to the state of IPL. Selection of odd or even parity is
controlled by the IOP bit.
LOPAIS:
The LOPAIS bit is an active high AIS insertion enable. When LOPAIS is set
high, AIS is automatically generated on the corresponding outgoing data
stream for all tributaries that are in loss of pointer state. When LOPAIS is set
low, the generation of AIS on the outgoing data stream is inhibited. This bit is
logically OR'ed with the bit of the same name in Tributary Alarm AIS Control
register.
IPE:
The IPE bit is an active high interrupt enable. When IPE is set high, the
occurrence of a parity error on the corresponding incoming parity signal set
will cause an interrupt to be asserted on the interrupt (INTB) output. When
IPE is set low, incoming parity errors will not cause an interrupt.
