3. DATA[15:8]/PG[7:0] and DATA[7:0]/PH[7:0] are only synchronized during reset and when being used as discrete
4. EXTAL, XFC, and XTAL are clock connections.
5. CS4 is used only on the MC68HC16Y3.
6. PAI and PCLK can be used for discrete input, but are not part of an I/O port.
7. PWMA and PWMB can be used for discrete input, but are not part of an I/O port.
Table 3-3 summarizes pin functions of the MC68HC16Y3 and MC68HC916Y3 MCUs.
Entries in the “Active State(s)” column denote the polarity of each MCU pin in its active
state. Some MCU pins have multiple functions and thus have multiple entries in the
“Active State(s)” column. For example, the ADDR23/CS10/ECLK pin can be pro-
grammed to be either address line 23 (ADDR23), chip-select output 10 (CS10), or the
M6800 bus clock (ECLK). Its entry in the “Active State(s)” column is “—/0/—” which
indicates the following:
The “Discrete I/O Use” column indicates whether each pin can be used as a general
purpose input, output, or both. Those pins that cannot be used for general purpose I/
O will have a “—” in this column.
