Table 2-3 Pin Names and Functions (2 of 6)
Port 43: Input/output port (with pull-up)
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 (with pull-up)
System clock output: Selectable between high- and low-speed clock outputs, as in the case of
CPU
Port 45: Input/output port (with pull-up)
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.
(After a reset operation is performed, it can be used as a port.)
Port 46: Input/output port (with pull-up)
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.
(After a reset operation is performed, it can be used as a port.) Input with Schmitt trigger
Port 47: Input/output port (with pull-up)
16-bit timer F output: Pin for outputting a 16-bit timer F
Port 5: Input/output port (with pull-up) 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 (with pull-up) 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 (with pull-up) 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) Input pin with Schmitt
trigger with Noise filter
Port 60: Input/output port (with pull-up)
Address: Address bus 8 (separate bus mode)
Sending serial data 0: Open drain output pin depending on the program used
Port 61: Input/output port (with pull-up)
Address: Address bus 9 (separate bus mode)
Receiving serial data 0
Interrupt request pin A: Selectable between "H" level, "L" level, rising edge, falling edge, and
both rising and falling edges.
Port 62: Input/output port (with pull-up)
Address: Address bus 10 (separate bus mode)
Serial clock input/output 0
Handshake input pin
Port 63: Input/output port (with pull-up)
Address: Address bus 11 (separate bus mode)
Sending serial data 1: Open drain output pin depending on the program used
Port 64: Input/output port (with pull-up)
Address: Address bus 12 (separate bus mode)
Receiving serial data 1
Interrupt request pin B: Selectable between "H" level, "L" level, rising edge, falling edge, and
both rising and falling edges.
