1. The frequency limitations in VLPR and VLPS modes here override any frequency specification listed in the timing

specification for any other module. These same frequency limits apply to VLPS, whether VLPS was entered from RUN

or from VLPR.

2. The LPTMR can be clocked at this speed in VLPR or VLPS only when the source is an external pin.

2.3.2 General switching specifications

These general-purpose specifications apply to all signals configured for GPIO and

UART signals.
