DF2211NP24V Renesas Technology / Hitachi Semiconductor, DF2211NP24V Datasheet - Page 265

• 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

Table 8.1 and table 8.2 summarize the port functions of the H8S/2218 Group and H8S/2212 Group
respectively. The pins of each port also have other functions such as input/output or external
interrupt input pins of on-chip peripheral modules. Each I/O port includes a data direction register
(DDR) that controls input/output, a data register (DR) that stores output data, and a port register
(PORT) used to read the pin states. The input-only ports do not have DR and DDR.
Ports A to E have an on-chip input pull-up MOS and a input pull-up MOS control register (PCR)
to control the on/off state of the input pull-up MOS. Ports 3 and A include an open-drain control
register (ODR) that controls the on/off state of the output buffer PMOS.
All the I/O ports can drive a single TTL load and 30-pF capacitive load.
