Function
Input
AA6 The incoming data parity #4 (IDP[4]) signal
carries the parity of the incoming signals for the
STM-1 #4 stream.
In incoming STM-1 (STS-3) interface mode
(IHSMODEB set high), the parity calculation
encompasses the ID[31:24] bus and optionally
the IC1J1[4] and the IPL[4] signals. IC1J1[4] and
IPL[4] can be included in the parity calculation
by setting the corresponding INCIC1J1 and
INCIPL register bits high, respectively. Odd
parity is selected by setting the corresponding
IOP register bit high, and even parity is selected
by setting the IOP bit low. IDP[4] is sampled on
the rising edge of SCLK.
In incoming STM-4 (STS-12) interface mode
(IHSMODEB set low), IDP[4] is unused and
must be strapped low.
