DESCRIPTION
EXTERNAL INTERRUPTS, CLOCK (CONTINUED)
XINT1/IOPA2
23
16
External user interrupt 1 or GPIO. Both XINT1 and XINT2
are
edge-sensitive.
The
edge
polarity
is
programmable.
(
↑)
XINT2/ADCSOC/IOPD0
21
15
42
External user interrupt 2 and ADC start of conversion or
GPIO. External “start-of-conversion” input for ADC/GPIO.
Both XINT1 and XINT2 are edge-sensitive. The edge
polarity is programmable.
(
↑)
CLKOUT/IOPE0
73
51
1
Clock output or GPIO. This pin outputs either the CPU clock
(CLKOUT) or the watchdog clock (WDCLK). The selection
is made by the CLKSRC bit (bit 14) of the system control
and status register (SCSR). This pin can be used as a GPIO
if not used as a clock output pin.
(
↑)
PDPINTB
137
95
Power drive protection interrupt input. This interrupt, when
activated, puts the PWM output pins (EVB) in the
high-impedance state should motor drive/power converter
abnormalities, such as overvoltage or overcurrent, etc.,
arise. PDPINTB is a falling-edge-sensitive interrupt.
(

OSCILLATOR, PLL, FLASH, BOOT, AND MISCELLANEOUS
XTAL1/CLKIN
123
87
24
PLL oscillator input pin. Crystal input to PLL/clock source
input to PLL. XTAL1/CLKIN is tied to one side of a reference
crystal.
XTAL2
124
88
25
Crystal output. PLL oscillator output pin. XTAL2 is tied to
one side of a reference crystal. This pin goes in the
high-impedance state when EMU1/OFF is active low.
PLLVCCA
12
10
39
PLL supply (3.3 V)
IOPF6
131
92
General-purpose I/O
(
↑)
BOOT_EN /
BOOT_EN
121
86
23
Boot ROM enable, GPO, XF. This pin will be sampled as
input (BOOT_EN) to update SCSR2.3 (BOOT_EN bit)
during reset and then driven as an output signal for XF. After
BOOT_EN /
XF
121
86
23
during reset and then driven as an output signal for XF. After
reset, XF is driven high. ROM devices do not have boot
ROM, hence, no BOOT_EN modes. The BOOT_EN pin
must be driven with a passive circuit only.
(
↑)
PLLF
11
9
38
PLL loop filter input 1
Bold, italicized pin names indicate pin function after reset.
GPIO General-purpose input/output pin. All GPIOs come up as input after reset.
§ It is highly recommended that VCCA be isolated from the digital supply voltage (and VSSA from digital ground) to maintain the specified accuracy
and improve the noise immunity of the ADC.
Only when all of the following conditions are met: EMU1/OFF is low, TRST is low, and EMU0 is high
# No power supply pin (VDD, VDDO, VCCA, VSS, or VSSO) should be left unconnected. All power supply pins must be connected appropriately for
proper device operation.
LEGEND:
↑ Internal pullup
↓ Internal pulldown
(Typical active pullup/pulldown value is
±16 A.)
