描述 Description

The EPD2012 is an 8-bit RISC MCU which embedded a 10 bits SAR A/D converter with
touch screen controller, an analog front end, 32 x 64 LCD driver, two 8-bit timers and
one 16-bit general timer with capture and event counter functions, IR generator,
Watchdog Timer, SPI, UART, four melody timers, a PWM and a current D/A. Besides,
it has an embedded large size user RAM and program/data memory. It is suitable for
educational learning tools application requiring high performance and low cost solution.
The MCU's core is ELAN's second generation RISC (RISC II) based IC. The core is
specifically designed as a low power and portable device. It supports Fast, Slow, and
Idle mode, as well as Sleep mode for low power consumption application.IMPORTANT NOTES?Do not use Register BSR (05h) Bit 7 ~ Bit 4.?Do not use Register BSR1 (07h) Bit 7 ~ Bit 4. ?Do not use Special Register (04h). ?Do not use Special Register (1Bh). ?Do not use Special Register (1Ch). ?Do not use Special Register (1Fh). ?Do not use Special Register (2Ah). ?Do not use Special Register (32h). ?Do not use Special Register (33h). ?Do not use Special Register (39h). ?Do not use Special Register (4Fh). ?Do not use LCD RAM Page 00 (40h~4Fh). ?Do not use LCD RAM Page 01 (40h~4Fh). ?Do not use LCD RAM Page 02 (40h~4Fh). ?Do not use LCD RAM Page 03 (40h~4Fh). ?Do not use LCD RAM Page 04 (40h~4Fh). ?Do not use LCD RAM Page 05 (40h~4Fh). ?Do not use Port B.3~4. ?Do not use Port C.0~1. ?Do not use Port D.0~3. ?Do not use JDNZ and JINZ at FSR1 (09h) special register. ?Do not use Register TABPTRH (0Dh) Bit 6.
