Register : Peripheral PLL Output Counter Reset Register - outrst

Description

Contains settings to assert individual Outreset for all Peripheral PLL Counters.

Bits Access Reset Description
[15:0] RW 0x0 Output Counter Reset
[31:16] ??? 0x0 UNDEFINED

Field : Output Counter Reset - outreset

Resets the individual PLL output counter.

For software to change the PLL output counter without producing glitches on the respective clock, SW must set the Output Counter Reset Register '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 Output Counter Reset bit.

LSB 'outreset[0]' corresponds to PLL output clock C0, etc.

If set to '1', reset output divider, no clock output from counter.

If set to '0', counter is not reset.

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

struct ALT_CLKMGR_PERPLL_OUTRST_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.
