9 / 100 page 9 MB90210 Series * : FPT-80P-M06, FPT-80C-C02 (Continued) Pin no. Pin name Circuit type Function QFP* 20 P40 E General-purpose I/O port This port is available when the UART (ch.2) serial data output from SOD3 is disabled either in the single-chip mode or when the upper address control register setting is “port.” A16 Output pin for external address bus A16 This pin is available when the UART (ch.2) serial data output from SOD3 is disabled in an external-bus mode and when the upper address control register setting is “address.” SOD3 UART (ch.2) serial data output pin (SOD3) This pin is available when the UART (ch.2) serial data output is enabled. 21 P41 E General-purpose I/O port This port is available when the UART (ch.2) clock output is disabled either in the single-chip mode or when the upper address control register setting is “port.” A17 Output pin for external address bus A17 This pin is available when the UART (ch.2) clock output is disabled in an external-bus mode and when the upper address control register setting is “address.” SCK2 UART (ch.2) clock output pin (SCK2) This pin is available when the UART (ch.2) clock output is enabled. UART (ch.2) external clock input pin (SCK2) This pin is available when the port is in input mode and the UART (ch.2) specification is external clock mode. 22 P42 E General-purpose I/O port This port is available in the single-chip mode or when the upper address control register setting is “port.” A18 Output pin for external address bus A18 This pin is available in an external-bus mode and when the upper address control register setting is “address.” SID2 UART (ch.2) serial data input pin (SID2) Since this input is used whenever the SID2 is in input operation, the output by any other function must be suspended unless the output is intentionally performed. 23 P43 E General-purpose I/O port This port is available when the UART (ch.2) serial data output from SOD2 is disabled either in the single-chip mode or when the upper address control register setting is “port.” A19 Output pin for external address bus A19 This pin is available when the UART (ch.2) serial data output from SOD2 is disabled in an external-bus mode and when the upper address control register setting is “address.” SOD2 UART (ch.2) serial data output pin (SOD2) This pin is available when the UART (ch.2) serial data output from SOD2 is enabled. |
