Z8^® MCU Microcontrollers
GENERAL DESCRIPTION (Continued)
By means of an expanded register file, the designer has
access to additional control registers for configuring per-
ipheral functions including the A/D and D/A converters,
counter/timers, and I/O port functions (Figure 1).
Notes: All Signals with a preceding front slash, "/", are
active Low, e.g., B//W (WORD is active Low); /B/W (BYTE
is active Low, only).
