8-bit programmable timer 2
• Clock supply to the Ch.0 serial interface
When using the Ch.0 serial interface in the clock-synchronized master mode or the internal clock-based
asynchronous mode, the output clock derived from the underflow signal of the 8-bit programmable timer
2 by dividing it by 2 is supplied to the serial interface as its operating clock. This enables the transfer rate
of the serial interface to be programmed.
To use this function, write "0" to the serial interface control bit SSCK0 (D2) / Serial I/F Ch.0 control
register (0x401E3) to select the internal clock.
8-bit programmable timer 3
• Clock supply to the Ch.1 serial interface
When using the Ch.1 serial interface in the clock-synchronized master mode or the internal clock-based
asynchronous mode, the output clock derived from the underflow signal of the 8-bit programmable timer
3 by dividing it by 2 is supplied to the serial interface as its operating clock. This enables the transfer rate
of the serial interface to be programmed.
To use this function, write "0" to the serial interface control bit SSCK1 (D2) / Serial I/F Ch.1 control
register (0x401E8) to select the internal clock.
8-bit programmable timer 4
• Clock supply to the Ch.2 serial interface
When using the Ch.2 serial interface in the clock-synchronized master mode or the internal clock-based
asynchronous mode, the output clock derived from the underflow signal of the 8-bit programmable timer
4 by dividing it by 2 is supplied to the serial interface as its operating clock. This enables the transfer rate
of the serial interface to be programmed.
To use this function, write "0" to the serial interface control bit SSCK2 (D2) / Serial I/F Ch.2 control
register (0x401F3) to select the internal clock.
8-bit programmable timer 5
• Clock supply to the Ch.3 serial interface
When using the Ch.3 serial interface in the clock-synchronized master mode or the internal clock-based
asynchronous mode, the output clock derived from the underflow signal of the 8-bit programmable timer
5 by dividing it by 2 is supplied to the serial interface as its operating clock. This enables the transfer rate
of the serial interface to be programmed.
To use this function, write "0" to the serial interface control bit SSCK3 (D2) / Serial I/F Ch.3 control
register (0x401F8) to select the internal clock.
