— Interchip bus interface for EEPROMs, LCD controllers, A/D converters, and keypads
— Fully compatible with industry-standard I2C bus
— Master and slave modes support multiple masters
— Automatic interrupt generation with programmable level
Queued serial peripheral interface (QSPI)
— Full-duplex, three-wire synchronous transfers
— Up to four chip selects available
— Master mode operation only
— Programmable bit rates up to half the CPU clock frequency
— Up to 16 pre-programmed transfers
Fast analog-to-digital converter (ADC)
— Eight analog input channels
— 12-bit resolution
— Minimum 1.125
s conversion time
— Simultaneous sampling of two channels for motor control applications
— Single-scan or continuous operation
— Optional interrupts on conversion complete, zero crossing (sign change), or under/over low/high limit
— Unused analog channels can be used as digital I/O
Four 32-bit timers with DMA support
— 12.5 ns resolution at 80 MHz
— Programmable sources for clock input, including an external clock option
— Programmable prescaler
— Input capture capability with programmable trigger edge on input pin
— Output compare with programmable mode for the output pin
— Free run and restart modes
— Maskable interrupts on input capture or output compare
— DMA trigger capability on input capture or output compare
Four-channel general purpose timer
— 16-bit architecture
— Programmable prescaler
— Output pulse-widths variable from microseconds to seconds
— Single 16-bit input pulse accumulator
— Toggle-on-overflow feature for pulse-width modulator (PWM) generation
— One dual-mode pulse accumulation channel
Pulse-width modulation timer
— Support for PCM mode (resulting in superior signal quality compared to conventional PWM)
— Operates as eight channels with 8-bit resolution or four channels with 16-bit resolution
— Programmable period and duty cycle
— Programmable enable/disable for each channel
— Software selectable polarity for each channel
— Period and duty cycle are double buffered. Change takes effect when the end of the current period is reached
(PWM counter reaches zero) or when the channel is disabled.
— Programmable center or left aligned outputs on individual channels
— Four clock sources (A, B, SA, and SB) provide for a wide range of frequencies
— Emergency shutdown
