S3C70F2/C70F4/P70F4
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:
— 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.
Three channels for analog input and one channel for external reference voltage input
Four channels for analog input and internal reference voltage level
