E.3.1.2.5 Transparent Mask Register (SCCM). This 8-bit register is located at offset $88A
(SCC1), $89A (SCC2), and $8AA (SCC3) on D15-D8 of a 16-bit data bus. The SCCM is
used to enable and disable interrupt events reported by the SCCE. The mask bits corre-
spond to the interrupt event bit shown in the SCCE. A bit should be set to a one to enable
the corresponding interrupt in the SCCE. Note that reserved bits in registers should be writ-
ten as zeros.
