# PSoC 6 Peripheral Driver Library v1.6.1

Please refer to the [README.md](./README.md) and the
[PDL API Reference Manual](https://cypresssemiconductorco.github.io/psoc6pdl/pdl_api_reference_manual/html/index.html)
for a complete description of the Peripheral Driver Library.

Some restrictions apply to the PSoC 64 devices configuration. Please refer to [PRA (Protected Register Access)](https://cypresssemiconductorco.github.io/psoc6pdl/pdl_api_reference_manual/html/group__group__pra.html) driver documentation for the details.

## New Features
Added support of the PSoC 64 CYB06xx7 devices.

## Updated Personalities

## Personalities with patch version updates

* HvIlo - Changed ILO frequency from 32 kHz to 32.768 kHz, and ILO accuracy from 30% to 10% to reflect the actual values.
* Csd - Fixed the CSD resource display condition on the Peripherals tab of the Device Configurator, to display this resource for all MPNs containing the CSD HW block.
* SysClock - Renamed cy_stc_pra_system_config_t member from altHFfreq to altHFclkFreq.
