Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

Bit Name Description Access Reset
27 phrst
If ictl_vpll_pr1_phrst_a=1'b1, the phase of PLLC1 clock is reset to default phase as the PLL is just started. 
Value Description
0 RSTDEASSERT
1 RSTASSERT
RW 0x0
26 phinc
When a positive edge is induced, one of the positive edges of PLLC1 clock is pushed out by 1/8th of VCO period. 
Value Description
0 UNPUSH
1 PUSH
RW 0x0
25 bypas
PLL channel 1 output bypass; before lock, it is muted, regardless of its value. After lock, if enabled and bypass=1, this outputs refclk. 
Value Description
0 UNBYPASS
1 BYPASS
RW 0x0
24 en
PLL channel 1 output enable; the output is muted before lock signal is asserted, regardless of the value; after lock is asserted, it is glitch-free enable ock_vpll_pr1, if enabled 
Value Description
0 DISABLE
1 ENABLE
RW 0x1
7:0 div
PLL channel 1 divider ratio in binary code; Can be dynamically updated after lock signal is asserted, glitch-free from 8'd3 to 8'd255; could encounter glitches for 8'd1 and 8d'2 cases.
