Table 23-15 shows the following options.
• FLAGS can be mapped to any of the AMI pins.
• PDAP data/control can be completely moved to AMI pins (instead
of DAI pins).
• PDAP, PWM signals can be mapped only to the upper bits of the
AMI address pins
• FLAGS/PWM can be mapped (in groups of four) to any of the
upper 31–16 AMI address pins.
