IR FUNCTION PINS
Digital, Active-Low, Reset Input/Output. The device remains in reset
as long as this pin is low and begins executing from the utility ROM at
address 8000h when this pin returns to a high state. The pin includes
pullup current source; if this pin is driven by an external device, it should
be driven by an open-drain source capable of sinking in excess of 4mA.
This pin can be left unconnected if there is no need to place the device in
a reset state using an external signal. This pin is driven low as an output
when an internal reset condition occurs.
High-Frequency Crystal Input. Connect an external crystal or resona-
tor between HFXIN and HFXOUT for use as the high-frequency system
clock. Alternatively, HFXIN is the input for an external, high-frequency
clock source when HFXOUT is unconnected.
IR Transmit Output. IR transmission pin capable of sinking 25mA. This
pin defaults to a high-impedance input with the weak pullup disabled
during all forms of reset. Software must configure this pin after release
from reset to remove the high-impedance input condition.
IR Receive Input. This pin defaults to a high-impedance input with the
weak pullup disabled during all forms of reset. Software must configure
this pin after release from reset to remove the high-impedance input
condition.
Port 0 General-Purpose, Digital I/O Pins. These port pins function as
general-purpose I/O pins with their input and output states controlled by
the PD0, PO0, and PI0 registers. All port pins default to high-impedance
mode after a reset. Software must configure these pins after release
from reset to remove the high-impedance condition. All alternate func-
tions must be enabled from software before they can be used.
