DF2211NP24V Renesas Technology / Hitachi Semiconductor, DF2211NP24V Datasheet - Page 440

• Manufacturer Part Number: DF2211NP24V
• Description: H8S/2200 Series, 2212 Group, USB, RTC, HSS TNP-64B; Vcc= 2.7 to 3.6 volts, Temp= -20 to 75 C; Package: PVQN0064LB-A
• Manufacturer: Renesas Technology / Hitachi Semiconductor

Note: * The average transfer rate select functions for 24 MHz only (ACS3 to ACS0 = B'10XX) are
12.3.10 Serial Extended Mode Register B_0 (SEMRB_0)
SEMRB_0 enables clock source selection with the combination of SEMRA_0, automatic transfer
rate setting, and control of port 1 pins (P16, P14, P12, and P10) at the transfer clock generation by
TPU.
Note: SEMRB_0 is not supported by the E6000 emulator.
