Circled characters indicate the Schmitt-trigger input. 2. BP0 through BP7 select VLC1 as an input source. However, the output levels change depending on the external circuit of BP0 through BP7 and VLC1. Example Because BP0 through BP7 are mutually connected inside the µPD753036, the output levels of BP0 through BP7 are determined by R1, R2, and R3. Programmable 4-bit input/output port (PORT6). This port can be specified for input/output bit-wise. Connections of on-chip pull-up resistors can be specified by software in 4-bit units. 4-bit input/output port (PORT7). Connections of on-chip pull-up resistors can be specified by software in 4-bit units. 4-bit input/output port (PORT8). Connections of on-chip pull-up resistors can be specified by software in 4-bit units. 1-bit output port (BIT PORT) Also used for segment output pins. PD753036 VLC1 R1 ON ON BP1 BP0 R2 R3 VDD µ |
