CY8C201A0-LDX2I Operating Modes of I2C Commands

CY8C201A0-LDX2I Operating Modes of I2C Commands
Normal Mode
In normal mode of operation, the acknowledgment time is
optimized. The timings remain approximately the same for
different configurations of the slave. To reduce the
acknowledgment times in normal mode, the registers
0x06–0x09, 0x0C, 0x0D, 0x10–0x17, 0x50, 0x51, 0x57–0x60,
0x7E are given only read access. Write to these registers can be
done only in setup mode.
Setup Mode
All registers have read and write access (except those which are
read only) in this mode. The acknowledgment times are longer
compared to normal mode. When CapSense scanning is
disabled (command code 0x0A in command register 0xA0), the
acknowledgment times can be improved to values similar to the
normal mode of operation.
