7.3.5
HFCGI Low Value Register (HFCGIL)
The HFCGIL Register is a byte-wide, read/write register con-
taining the lower eight bits of the frequency multiplier HFCGI
value. Data written to the register is stored in the setup buffer.
Reading the register returns the value of its first 8 bits. (The
IVLID bit in the HFCGCTRL Register indicates if the data is
valid.)
7.3.6
HFCGI High Value Register (HFCGIH)
The HFCGIH Register is a byte-wide, read/write register
containing the upper six bits of the frequency multiplier
HFCGI value. Data written to the register is stored in the
setup buffer. Reading the register returnees the current sta-
tus of the frequency set registers.
