7 Frame Group and FG I/O
7.1 Frame Group Control Registers
7.1.2 FGx Width Registers
The FGx width registers control the polarity and the pulse widths generated for the corresponding frame group bit.
The pulse-width programming works in conjunction with the FGx rate registers to provide 1-bit, 2-bit, 4-bit,
1-byte, and 2-byte wide pulses for any of the available frame group rates (see Table 59).
Table 59. FGx Width Registers
7.1.3 FGx Rate Registers
The FGx rate registers either enable FGIO operation* or work in conjunction with FGx width registers to provide
various width frame group pulses at rates of 2.048 MHz, 4.096 MHz, 8.192 MHz, or 16.384 MHz.
Table 60. FGx Rate Registers
* FGIO operation is controlled at registers 0x00480—482. Refer to Section 7.3 on page 75.
