Features
• Bus-busy detection
2.4.18 Real Time Counter (RTC)
The Real Timer Counter supports wake-up from Low Power modes or Real Time Clock generation
• Configurable resolution for different timeout periods
— 1 s resolution for >1 hour period
— 1 ms resolution for 2 second period
• Selectable clock sources from external 32 KHz crystal, external 4–16 MHz crystal, internal
128 kHz RC oscillator or divided internal 16 MHz RC oscillator
2.4.19 Enhanced Modular Input/Output System (Timers, PWM)
PXD10 microcontrollers have two eMIOS modules—one with 16 channels and one with 8—with
input/output channels supporting a range of 16-bit input capture, output compare, and Pulse Width
Modulation functions.
The modules are configurable and can implement 8-channel, 16-bit input capture/output compare or
16-channel, 16-bit output pulse width modulation/input compare/output compare. Up to five additional
channels are configurable as modulus counters.
eMIOS features include:
• Selectable clock source from main FMPLL, auxiliary FMPLL, external 4–16 MHz oscillator or
16 MHz Internal RC oscillator
• Timed I/O channels with 16-bit counter resolution
• Buffered updates
• Support for shifted PWM outputs to minimize occurrence of concurrent edges
• Edge aligned output pulse width modulation
— Programmable pulse period and duty cycle
— Supports 0% and 100% duty cycle
— Shared or independent time bases
• Programmable phase shift between channels
• Selectable combination of pairs of eMIOS outputs to support sound generation
• DMA transfer support
• Selectable clock source from the primary FMPLL, auxiliary FMPLL, external 4–16 MHz
oscillator or the 16 MHz internal RC oscillator.
The channel configuration options for the 16-channel eMIOS module are summarized in Table 3.
