General Release Specification
General Description
NON-DISCLOSURE
AGREEMENT
REQUIRED
1.6 RESET
Driving this input low will reset the MCU to a known startup state. The
RESET pin contains an internal Schmitt trigger to improve its noise
immunity. Refer to Section 5. Resets.
1.6.1 PA0–PA7
These eight I/O pins comprise port A. The state of any pin is software
programmable, and all port A lines are configured as inputs during
power-on or reset. Eight individual mask options can be chosen to
enable pullups and interrupts (active low) on each port A pin. Refer to
1.6.2 PB5, PB6, and PB7
These three I/O pins comprise port B. The state of any pin is software
programmable and all port B lines are configured as inputs during
power-on or reset. Refer to Section 7. Input/Output Ports.
1.6.3 PC0–PC7
These eight I/O pins comprise port C. The state of any pin is software
programmable and all port C lines are configured as inputs during
power-on or reset. PC0 and PC1 are capable of sourcing and sinking
more current than a typical I/O pin. Refer to Section 7. Input/Output
1.6.4 PD5 and PD7/TCAP
These two pins comprise port D and are shared with the 16-bit timer
subsystem. The state of PD5 is software programmable and is
configured as an input during power-on or reset. PD7 is always an input.
It may be read at any time, regardless of the mode of operation of the
16-bit timer. Refer to Section 7. Input/Output Ports and Section 8. 16-
