Description
I/O Port 7, Bypass I/Os
Port 7 is a dedicated 8-bit bidirectional I/O port. The user can select
between an input, totem pole output, or open-drain or open-source
output. Capability to detect input edge changes and select various
output flashing rates is also available.
Through bit control register setup, each odd-numbered bit of this port
can be enabled as an output, which on a pair-by-pair basis, reflects the
current state of each even-numbered bit of this port. Individual control
is provided that allows programming each output as a totem pole or an
open-drain/source driver.
