SYSRST:
System reset
0: No reset performed (initial value)
1: Reset all circuits other than the command registers.
PDOWN[1:0]:
Low power mode settings (Only specific functions are enabled.)
00: Normal operation (initial value)
01: Only the oscillator amplifier is enabled.
10: Only the oscillator amplifier and the output clock divider are enabled.
11: Reserved
PLLOPR:
PLL (VCO) operate/stop setting
0: Operate (initial value)
1: Stop
PLLCK[1:0]:
Clock frequency setting in the PLL locked state
00: 256fs (initial value)
01: 384fs
10: 512fs
11: (512/2)fs = 256fs
MCKHFO:
Frequency setting of CKOUT output clock
0: 1/1 output (initial value)
1: 1/2 output
It is possible to maintain clock continuity when switching from the 512fs setting with PLLCK[1:0] = "10" to the
(512/2) fs setting with PLLCK[1:0] = "11", and switching vice versa without entering the PLL lock error state.
For systems that must minimize power consumption such as portable equipment, we recommend the PLLCK[1:0] =
"00" (256fs) setting. For systems that require improved performance such as AV amplifiers, we recommend the
PLLCK[1:0] = "10" (512fs) or PLLCK[1:0] = "11" (512/2fs) setting.
