6 / 15 page ![]() 6/15 ¡ Semiconductor MSM65352/65352B Function Pin Type Description 8-bit Input-output port (port 0): Each of bits 0 to 7 is configured to be an input or an output by the direction register of port 0 (P0DIR). In addition to the basic function as the Input-output port, a secondary function is allocated to each of P0.0 through P0.7. Refer to the next table. 1 I/O Port 8 to 8-bit Input-output port (port 1): Each of bits 0 to 7 is configured to be input or output by the direction register of port 1 (P1DIR). In addition to the basic function as the Input-output port, a secondary function is allocated to each of P1.0 through P1.7. Refer to the next table. 56 I/O 63 to Input port (port 2.0) I 55 O 54 Output port (port 2.1) Pulled high at the time of reset. If this pin is set to the "0" level during reset, this IC goes into a test mode, disabling execution of the user program. Input-output port (port 2.2) I/O 53 O 4-bit output port: These pins are valid only for the MSM65352. 52 49 to O LCD common signal output pins 32 29 to O LCD segment signal output pins In the case of MSM65352B, SEG0 to SEG19 and Pin 33 to Pin 52 are used. 48 33 to LCD Driver Symbol P0.7 P0.0 to P1.7 P1.0 to P2.0 (IN) P2.1 (TEST) P2.2 P4.3 P4.0 to COM4 COM1 to SEG15 SEG0 to I 8-bit input port (port 3): Each of P3.0 to P3.7 functions as analog input channel of A/D converter. 16 23 to P3.7 P3.0 to Basic Function (Continued) |
