Table 2-3 Pin names and functions (2/8)
Pin for setting an external bus mode: This pin functions as a
multiplexed bus by sampling the "H (DVCC3) level" at the rise of
a reset signal. It also functions as a separate bus by sampling
"L" at the rise of a reset signal. When performing a reset
operation, pull it up or down according to a bus mode to be used.
Input with Schmitt trigger.
This pin is used to set a mode. It performs a big-endian
operation by sampling the "H (DVCC3) level" at the rise of a
reset signal, and performs a little-endian operation by sampling
"L" at the rise of a reset signal. When performing a reset
operation, pull it up or down according to the type of endian to be
used.
Port 40: Input/output port
Chip select 0: "0" is output if the address is in a designated
address area.
KEY on wake up input 24: (Dynamic pull up is selectable)
Port 41: Input/output port
Chip select 1: "0" is output if the address is in a designated
address area.
KEY on wake up input 25: (Dynamic pull up is selectable)
Port 42: Input/output port
Chip select 2: "0" is output if the address is in a designated
address area.
KEY on wake up input 26: (Dynamic pull up is selectable)
Port 43: Input/output port
Chip select 3: "0" is output if the address is in a designated
address area.
KEY on wake up input 27: (Dynamic pull up is selectable)
Port 44: Input/output port
System clock output: Selectable between high- and low-speed
clock outputs, as in the case of CPU
Port 45: Input/output port
(After a reset operation is performed, it can be used as a port.)
Port 46: Input/output port
(After a reset operation is performed, it can be used as a port.)
Port 47: Input/output port
16-bit timer F output: Pin for outputting a 16-bit timer F
Port 5: Input/output port that allows input/output to be set in
units of bits
Address: Address buses 0 to 3 (separate bus mode)
Interrupt request pins C to F: Selectable between "H" level, "L"
level, rising edge, and falling edge
Port 5: Input/output port that allows input/output to be set in
units of bits
Address: Address buses 4 and 5 (separate bus mode)
16-bit timer 0 output: Pin for outputting a 16-bit timer 0
16-bit timer 1 output: Pin for outputting a 16-bit timer 1
Port 5: Input/output port that allows input/output to be set in
units of bits
Address: Address buses 6 and 7 (separate bus mode)
16-bit timer 2 output: Pin for outputting a 16-bit timer 2
16-bit timer 3 output: Pin for outputting a 16-bit timer 3
KEY on wake up input 28 and 29: (Dynamic pull up is
selectable)
