Peripherals
ADC - Up to 16-channel, 10-bit analog-to-digital converter with automatic compare function
SCI - Two serial communications interface modules with optional 13-bit break
SPI - Serial peripheral interface module
IIC - Inter-integrated circuit bus module to operate at up to 100 kbps with maximum bus loading; capable of higher baud rates with reduced loading
Timers - One 2-channel and one 6-channel 16-bit timer/pulse-width modulator (TPM) module: Selectable input capture, output compare, and edge-aligned PWM capability on each channel. Each timer module may be configured for buffered, centered PWM (CPWM) on all channels
KBI - Up to 8-pin keyboard interrupt module
Input/Output
Up to 54 general-purpose input/output (I/O) pins
Software-selectable pullups on ports when used as inputs
Software-selectable slew rate control on ports when used as outputs
Software-selectable drive strength on ports when used as outputs
Master reset pin and power-on reset (POR)
Internal pullup on RESET, IRQ, and BKGD/MS pins to reduce customer system cost
