12MHz crystal, or oscillator input
12MHz crystal output
Digital ground
External MCU serial bus data pin
External MCU serial bus clock pin
Test mode select pin; pull low in normal operation
External MCU clock pin; clock frequency is programmable
(12MHz, 6MHz, 3MHz, 1.5MHz)
Default is 1.5 MHz
External MCU interrupt pin (active L)
When internal register address 0 ~ 3 or external serial EEPROM is accessed,
MINT is set low; after MCU read, MINT is reset to H
