Table 22.16 Permissible Output Currents - Hitachi SH7750 Hardware Manual

Notes: 1. Connect V
regardless of whether or not the PLL circuits and RTC are used.
2. The current dissipation values are for V
output pins unloaded.
3. I is the sum of the V
DDQ
* To reduce the leakage current in standby mode, the RTC must be turned on (input the
clock from EXTAL2 and set RCR2.RTCEN to 1).
