MAXQ7667 User’s Guide
The MAXQ7667 peripheral register space (modules 0 to 5) contains registers that access the following peripherals:
• Two general-purpose, 8-bit, I/O ports (P0, P1)
• External interrupts (up to 16)
• Three programmable Type 2 timer/counters
• LIN-compatible UART interface
• SPI
• Analog module (SAR ADC and ultrasonic measurement)
• Hardware multiplier
• JTAG debug engine
• Schedule timer
The lower 8 bits of all registers in modules 0 to 5 (as well as the AP module M8) are bit addressable.
