Chapter 2 – SocketModem (MT5600SMI & MT5656SMI) SCR – Scratch Register (Addr = 7) The Scratchpad Register is a read-write register at location 7. This register is not used by the modem and can be used by the host for temporary storage. Divisor Registers (Addr = 0 and 1, DLAB = 1) The Divisor Latch LS (least significant byte) and Divisor Latch MS (most significant byte) are two read-write registers at locations 0 and 1 when DLAB = 1, respectively. The baud rate is selected by loading each divisor latch with the appropriate hex value. Programmable values corresponding to the desired baud rate are listed in Table on following page.
