• Bit 14—PA15 Mode (PA15MD): Selects the function of the PA15/CK pin.
Bit 14: PA15MD Description
0
General input/output (PA15) (single chip mode initial value)
1
Clock output (CK) (extended mode initial value)
• Bit 13—Reserved: This bit always reads as 0. The write value should always be 0.
• Bit 12—PA14 Mode (PA14MD): Selects the function of the PA14/RD pin.
Bit 12: PA14MD Description
0
General input/output (PA14) (initial value) (RD in on-chip ROM invalid mode)
1
Read output (RD) (PA14 in single chip mode)
• Bit 11—Reserved: This bit always reads as 0. The write value should always be 0.
• Bit 10—PA13 Mode (PA13MD): Selects the function of the PA13/WRH pin.
Bit 10: PA13MD Description
0
General input/output (PA13) (initial value) (WRH in on-chip ROM invalid mode)
1
Most significant side write output (WRH) (PA13 in single chip mode)
• Bit 9—Reserved: This bit always reads as 0. The write value should always be 0.
• Bit 8—PA12 Mode (PA12MD): Selects the function of the PA12/WRL pin.
Bit 8: PA12MD
0
1
Description
General input/output (PA12) (initial value) (WRL in on-chip ROM invalid mode)
Least significant side write output (WRL) (PA12 in single chip mode)
• Bit 7—Reserved: This bit always reads as 0. The write value should always be 0.
• Bit 6—PA11 Mode (PA11MD): Selects the function of the PA11/CS1 pin.
Bit 6: PA11MD
0
1
Description
General input/output (PA11) (initial value) (CS1 in on-chip ROM invalid mode)
Chip select output (CS1) (PA11 in single chip mode)
• Bit 5—Reserved: This bit always reads as 0. The write value should always be 0.
