Register : SDRAM PLL Output Counter Reset Ack Status Register - stat

Description

Contains Output Clock Counter Reset acknowledge status.

Register Layout

Bits Access Reset Description
[5:0] R 0x0 Output Counter Reset Acknowledge
[31:6] ??? 0x0 UNDEFINED

Field : Output Counter Reset Acknowledge - outresetack

These read only bits per PLL output indicate that the PLL has received the Output Reset Counter request and has gracefully stopped the respective PLL output clock.

For software to change the PLL output counter without producing glitches on the respective clock, SW must set the VCO register respective Output Counter Reset bit. Software then polls the respective Output Counter Reset Acknowledge bit in the Output Counter Reset Ack Status Register. Software then writes the appropriate counter register, and then clears the respective VCO register Output Counter Reset bit.

The reset value of this bit is applied on a cold reset; warm reset has no affect on this bit.

Data Structure Documentation

struct ALT_CLKMGR_SDRPLL_STAT_s

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
