Freescale Semiconductor 35
Preliminary
PWMA0 62 Output In reset,
output is
disabled,
pull-up is
enabled
PWMA0 - 5 — These are six PWMA outputs.
PWMA1 64
PWMA2 65
PWMA3 67
PWMA4 68
PWMA5 70
ISA0
(GPIOC8)
113 Schmitt

Schmitt
Input/
Output
Input,
pull-up
enabled
ISA0 - 2 — These three input current status pins are used for
top/bottom pulse width correction in complementary channel
operation for PWMA.
Port C GPIO — These three GPIO pins can be individually
programmed as input or output pins.
In the 56F8346, these pins default to ISA functionality after reset.
In the 56F8146, the default state is not one of the functions offered
and must be reconfigured.
To deactivate the internal pull-up resistor, clear the appropriate bit
of the GPIOC_PUR register. For details, see Part 6.5.8.
ISA1
(GPIOC9)
114
ISA2
(GPIOC10)
115
FAULTA0 71 Schmitt
Input
Input,
pull-up
enabled
FAULTA0 - 2 — These three fault input pins are used for disabling
selected PWMA outputs in cases where fault conditions originate
off-chip.
To deactivate the internal pull-up resistor, set the PWMA0 bit in the
SIM_PUDR register. For details, see Part 6.5.8.
FAULTA1 73
FAULTA2 74
PWMB0 34 Output In reset,
output is
disabled,
pull-up is
enabled
PWMB0 - 5 — Six PWMB output pins.
PWMB1 35
PWMB2 36
PWMB3 39
PWMB4 40
PWMB5 41
