SCC Programming Reference
E.2.1.2.3 SCC Data Synchronization Register (DSR). This 16-bit register is located at off-
set $886 (SCC1) $896 (SCC2) and $8A6 (SCC3). Bits 14-12 of the DSR are used to pro-
gram the length of the last stop bit transmitted. These bits are decoded as follows:
DSR(14-12)—Fractional Stop Bits
E.2.1.2.4 UART Event Register (SCCE). This 8-bit register is located at offset $888
(SCC1) $898 (SCC2) and $8A8 (SCC3) on D15-D8 of a 16-bit data bus. The SCCE is used
to report events recognized by the UART channel. Bits must be cleared by the user to avoid
missing interrupt events. Bits are cleared by writing ones to the corresponding bit positions.
