David Fries 40f0fae5a4 Update manpage for USBtiny and direct SPI 2022-01-09 10:57:22 +01:00
David Fries cffa6c7ca0 Add direct SPI mode to USBtiny
It is limited to exactly sending (and receiving) multiples of 4 bytes,
and unlike programming mode where slave select isn't required, SS must
be held low for SPI to work. USBtiny programmers don't usually have
a wire for SS.

David Fries 112b6edd1c Set back to programming mode on quit
Otherwise it can't read the fuses and the safe fuse code complains.
