Details of Change
De-documented all Transport Path Overhead port (TPOH) functionality
Added Overhead byte processing information in operation section.
• Removed TIU2E and TIU2I registers bits from registers 1n2Dh and 1n31h
respectively.
• DOPJ[1:0] register bit in the TTAL block (register 1nD1h) have been removed.
• DOPJ[1:0] register bit in the RTAL block (register 1n59h) have been redefined.
• PRBS monitoring mode needs two bits to be programmed. Mode setting in
both the DPGM (register 1n7Ah) and APGM (register 1nFAh) is now defined via
two mode bits MON_GMODE[1:0].
• RSOP Section B1 error counters (0m16h and Om17h registers) may also be
transferred upon a write to either register.
• Master test register bit 3 to 7 are defined as R/W instead of just W.
• Pin out diagram has changed format to improve readibility but the pinout
remains the SAME.
• Due to clear on write auxiliary interrupts, tZint timing is specified for
microprocessor writes to clear device interrupt pin.
• Analog supplies AVD/AVS are specified at 5% instead of 10%.
• Consistent naming or STM1-CONCAT to STM1_CONCAT (underscore) register
bit in registers 1n00h and 1n80h.
• Power supply board recommendations have been changed in section 13.8.
Separate supplies are no longer recommended.
• Specific PECL input currents are given in section 17, D.C. Characteristics.
• RAD does not contain transmitted K1/K2 bytes under generation of AIS-L on
the transmit stream.
• TAD port is limited to accumulating a maximum of 15 REI
• Additional feature explanations/ clarifications
• Timing Change on drop interface in 19.44 Mhz mode
• Addition of register bits CONCAT, TPOH_DIS, ATSI_FORCE and ATSI_RESET
• Definition changes of LOPCONRALM and PAISCONRALM.
• Added Section describing loopbacks
• DC Characteristics up to date and complete
• Added RTC_EN register bit.
