• Manufacturer Part Number: PEB2075
• Description: ICs for Communications Extended PCM Interface Controller
• Manufacturer: INFINEON [Infineon Technologies AG]

Based on these PCM and CFI timing requirements, the following EPIC initialization
values for the PCM and CFI registers are recommended:
EPIC
PBNR = 1111 1111
POFD = 1111 0000
POFU = 0001 1000
PCSR = 0000 0001
CMD1 = 0010 0000
CMD2 = 1101 0000
CBNR = 1111 1111
