There is no PIN caching at all.  The card itself does what you call
"caching": As soon as you send a VERIFY command to the card (with the
PIN) the card enters a state which allows operation requiring this
VERIFY command until a reset or power-down.  This is detailed in the

There is no command to explicitly do that.  You may run "gpgconf
--reload scdaemon" to power down the card.
