Handling of Unused Pins
Table 4.3 shows a handling of unused pins of the RZ/G1M.
"Unused pin" means all modules that are multiplexed to the pin should be disable and unused in this section. For
handling of some unused pin which belongs to the enable module should be handled following the notification of the
module manual. Unless otherwise specified in the module manual, follow the Table 4.3 for handling of unused pins.
[Legend]
No.: Serial number, Pin No.: BGA package ball grid number, Pin Name: Pin name of function 1 in pin multiplex
table, I/O: Input or output direction considered about all multiplexed pin functions of the pin.
Mode Pin: All mode pins must be used during power-on reset.
Boot: These pins must be used in boot operation (LBSC area 0 or QSPI).
Default pull-up: Internal pull-up control function is available or not from a power-on reset and its pull-up state.
"On": Pull-up control function is available and default state is pulled-up.
(No.212, ACK pin is available 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).
Notes: 1. All power supply pins and ground pins include VCCQ, VCCQ18, VDD, VDD_DVFS, VDDQ_M0,
VDDQ_M1, VDDQ_M1A and VSS pins must be used.
2. All mode pins (MD[14:0], [24:19], [28:27] and MDT[1:0]) must be used during power-on reset. For details of
mode pin setting, refer to section 3.3, Mode Pin Settings.
3. Boot module related pins (LBSC or QSPI) should be used during boot operation. For details of QSPI boot,
refer to section 18, Booting.
4. Refer to Table 4.1, List of Multiplexed Pin Functions for multiplexed pin and module of each pin.
