6. IOCD (Pull-high Control Register)
7. IOCE (WDT Control Register)
8. IOCF (Interrupt Mask Register)
• IOCC Register is both readable and writable.
• Bit 0 (/PH0) Control bit used to enable the pull-high of P60 pin.
• Bit 1 (/PH1) Control bit is used to enable the pull-high of P61 pin.
• Bit 2 (/PH2) Control bit is used to enable the pull-high of P62 pin.
• Bit 3
• Bit 4 (/PH4) Control bit is used to enable the pull-high of P64 pin.
• Bit 5 (/PH5) Control bit is used to enable the pull-high of P65 pin.
• Bit 6 (/PH6) Control bit is used to enable the pull-high of P66 pin.
• Bit 7 (/PH7) Control bit is used to enable the pull-high of P67 pin.
• IOCD Register is both readable and writable.
• Bit 7 (WDTE) Control bit used to enable Watchdog timer.
• Bit 6 (EIS) Control bit is used to define the function of P60(/INT) pin.
• Bits 0~5 Not used.
• Bit 0 (TCIE) TCIF interrupt enable bit.
0: Enable internal pull-high
1: Disable internal pull-high
0: Disable WDT.
1: Enable WDT.
WDTE is both readable and writable.
0: P60, bi-directional I/O pin.
1: /INT, external interrupt pin. In this case, the I/O control bit of P60 (bit 0 of IOC6) must be set to "1".
When EIS is "0", the path of /INT is masked. When EIS is "1", the status of /INT pin can also be read
by way of reading Port 6 (R6). Refer to Fig. 7.
EIS is both readable and writable.
0: disable TCIF interrupt
