PRODUCT OVERVIEW

BIT SEQUENTIAL CARRIER

The bit sequential carrier (BSC) is a 16-bit register that can be manipulated using 1-, 4-, and 8-bit instructions.

Using 1-bit indirect addressing, addresses and bit locations can be specified sequentially. In this way, programs

can process 16-bit data by moving the bit location sequentially and then incrementing or decrementing the value

of the L register. BSC data can also be manipulated using direct addressing.

COMPARATOR

The S3C70F2/C70F4 contains a 4-channel comparator which can be multiplexed to normal input port.

— Conversion time: 15.2 µs, 121.6 µs at 4.19 MHz

— Two operation modes:

Three channels for analog input and one channel for external reference voltage input

Four channels for analog input and internal reference voltage level

— 16-level internal reference voltage generator

— 150 mV accuracy for input voltage level difference detection (maximum)

— Comparator enable and disable

The comparison results are read from the 4-bit CMPREG register after the specified conversion time.
