(a) CSR1011 QFN is reliable and qualifiable to 4.3V (idle, active and deep sleep modes) and 3.8V (all modes), but there are minor deviations in
performance relative to published performance values for 1.8V to 3.6V. For layout guidelines for 4.3V operation, see CSR1011 Hardware Design
Review Template.
(b) During Run mode, see Section 4.1.
