input bandwidth

send. Keep the EP1 descriptors around (commented out) in case we need
them later, e.g., for interrupts.

AT86RF230_BUF_READ

- fw/atspi/atspi.c (init_io): added #ifdef'ed-out code to disable the
pull-ups, and an explanation why we can't do this.

transceiver's ID registers
- fw/atspi/atspi.c (init_io): comment had the wrong initial value for SCLK
- fw/atspi/atspi.c (init_io): xxx_MODE are registers, not bits ...
- fw/common/io.h (IRQ_RF), fw/atspi/atspi.c (init_io): indicate pending
moving of IRQ_RF
command-line utility to retrieve it.

f32xbase)

config.h and which was enabled by accident only
accident
