Architectural Overview
â GPIOs
â 0-36 GPIOs, depending on configuration
â 5-V-tolerant input/outputs
â Programmable interrupt generation as either edge-triggered or level-sensitive
â Bit masking in both read and write operations through address lines
â Programmable control for GPIO pad configuration:
⢠Weak pull-up or pull-down resistors
⢠2-mA, 4-mA, and 8-mA pad drive
⢠Slew rate control for the 8-mA drive
⢠Open drain enables
⢠Digital input enables
â Power
â On-chip Low Drop-Out (LDO) voltage regulator, with programmable output user-adjustable
from 2.25 V to 2.75 V
â Low-power options on controller: Sleep and Deep-sleep modes
â Low-power options for peripherals: software controls shutdown of individual peripherals
â User-enabled LDO unregulated voltage detection and automatic reset
â 3.3-V supply brown-out detection and reporting via interrupt or reset
â Flexible Reset Sources
â Power-on reset (POR)
â Reset pin assertion
â Brown-out (BOR) detector alerts to system power drops
â Software reset
â Watchdog timer reset
â Internal low drop-out (LDO) regulator output goes unregulated
â Additional Features
â Six reset sources
â Programmable clock source control
â Clock gating to individual peripherals for power savings
