Note: Pin numbers in parentheses () indicate signal grounds.
(2) Output Signals
Note 1. The pin number in parentheses is the common ground for output signals (COM_SG).
2. The functions allocated to /TGON, /S-RDY, and /V-CMP (/COIN) output signals can be changed by using the
parameters. Refer to 3.3.2 Output Signal Allocations for details.
