4. Pin Multiplexing
4.1
List of Multiplexed Pin Functions
Table 4.1 lists the multiplexed pin functions of the RZ/G1M.
The default pin function of each pin after power-on reset is "Function 1" respectively, unless otherwise mentioned in
each table note.
For details on pin function control, refer to section 3.3, Mode Pin Settings and section 5, Pin Function Controller (PFC).
[Legend]
No.: Serial number, Pin No.: BGA package ball grid number, Mode Pin (only for corresponding pin): Mode pin is
assigned, Function n (n=1, 2, 3, ...)/GPIO: Module or GPIO, Module: Module abbreviation except for GPIO, Pin
Name: Module or GPIO pin name, I/O: Input or output
"Reserved" in module column is assigned internal function and "-" in module column is undefined, they must not be
specified.
During POR: Pin state during power-on reset (PRESET# pin input is low-level).
V/|IOH|: Pin voltage and output drive current (nominal value respectively).
Pull-up: Internal pull-up control function is available or not from a power-on reset.
"On": Pull-up control function is available and default state is pulled-up.
(No.212, ACK pin is available for internal pull-down function.)
"Off": Pull-up control function is available and default state is not pulled-up.
"-": Pull-up control function is not available.
For details of pull-up control function, refer to PUPR0 through PUPR7 registers in section 5, Pin Function
Controller (PFC).
I: Input, I(S): Schmitt input, IO: Input and output, IO (OD): Input and open drain output, O: Output, P: Power supply pin.
(H)/(L)/(X)/(Z) in I/O row: Default pin state (only for default pin, except for clock or analog output)
H: High level output, L: Low level output, X: Undefined value output, Z: High impedance
Notes:
1. All power supply pins and ground pins must be supplied suitable power supply and GND respectively.
2. All mode pins must be used during power-on reset.
3. Pin name that has an identifier for example "XXXX_B", "XXXX_C" etc. are mirror pins of the XXXX pin.
Only one pin out of the XXXX pin or its mirror pins can be used. When using mirror pin, specify the suite of
pin that has the same identifier for the selected module. It is prohibited to use a suite of pin as mixed two or
more identifiers for a selected module.
4. Do not use any pins that of unused modules.
5. Unused pins must be handled as described in section 4.3, Handling of Unused Pins.
6. The terminal state after the reset cancellation has been described as a premise not using the BKPRST
(BKRST#=H(fixed)).
