PIN #
Internal/External Oscillator Input. To use the internal oscillator, a quartz crystal or a ceramic
resonator may be connected across X1 and X2. The X1 pin is referenced to the 1.8-V core digital
power supply. A 1.8-V external oscillator may be connected to the X1 pin. In this case, the XCLKIN
pin must be connected to ground. If a 3.3-V external oscillator is used with the XCLKIN pin, X1 must
be tied to GND. (I)
Internal Oscillator Output. A quartz crystal or a ceramic resonator may be connected across X1 and
X2. If X2 is not used it must be left unconnected. (O)
RESET
Device Reset (in) and Watchdog Reset (out).
Device reset. XRS causes the device to terminate execution. The PC will point to the address
contained at the location 0x3FFFC0. When XRS is brought to a high level, execution begins at the
location pointed to by the PC. This pin is driven low by the DSP when a watchdog reset occurs.
During watchdog reset, the XRS pin is driven low for the watchdog reset duration of 512 OSCCLK
cycles. (I/OD,
↑
)
The output buffer of this pin is an open-drain with an internal pullup (100
μ
A, typical). It is
recommended that this pin be driven by an open-drain device.
