Detailed Description

SPI Communication Parameters.

MAX22200 SPI protocol (per datasheet Rev 1, 3/25):

• SPI Mode 0: CPOL=0, CPHA=0
• Maximum SPI clock: 10 MHz (standalone), 5 MHz (daisy-chain)
• Two-phase protocol: Phase 1: CMD pin HIGH → write 8-bit Command Register Phase 2: CMD pin LOW → read/write 8 or 32 bits of data
• Registers are 32-bit (or 8-bit MSB-only mode)
