描述 Description

The ePS6610 is an 8-bit RISC MCU embedded with a 5 x 40 LCD driver along with two 8-bit timers, one 16-bit general timer, and a watchdog timer. It has also on-chip 1.2K bytes RAM and 8K words program ROM. It is highly ideal for advance scientific calculator application, particularly those requiring high performance and low cost solution. The MCU core is one of ELAN's second generation RISC based IC's, known as RISC II (RII) series. The core was specifically designed for low power and portable device applications. The ePS6610 also supports Fast, Slow, and Idle modes, as well as Sleep mode to enhance its low power consumption features.

應(yīng)用 Application

. The ePS6610 also supports Fast, Slow, and Idle modes, as well as Sleep mode to enhance its low power consumption features. IMPORTANT NOTES  Do not use Register BSR (05h) Bit 7 ~ Bit 4.
 Do not use Register BSR1 (07h) Bit 7 ~ Bit 4.
 Check the range of BSR and BSR1, which should be from 0x00~0x09.
 Do not use LCD RAM 28h ~ FFh.
 Do not use JDNZ at FSR1 (04h) special register.
 Do not use JDNZ at LCDARL (09h) special register.
 Do not use PUSH, POP by \"MOV A.r\" to avoid effecting S_Z.
