261 / 1075 page  Section 8 I/O Ports Rev. 3.00 Jan 18, 2006 page 233 of 1044 REJ09B0280-0300 8.7.3 Pin Functions Port 6 pins also function as the 16-bit free-running timer (FRT) I/O pins (FTOA, FTOB, FTIA to FTID, FTCI), timer X (TMRX) I/O pins (TMOX, TMIX), the timer Y (TMRY) input pin (TMIY), timer connection I/O pins (HFBACKI, VSYNCI, VSYNCO, VFBACKI, CLAMPO), key-sense interrupt input pins ( KIN7 to KIN0), expansion A/D input pins (CIN7 to CIN0), and interrupt input pins ( IRQ7, IRQ6). The port 6 input level can be switched in four stages. The port 6 pin functions are shown in table 8.13. Table 8.13 Port 6 Pin Functions Pin Selection Method and Pin Functions P67/TMOX/ IRQ7/ KIN7/CIN7 The pin function is switched as shown below according to the combination of bits OS3 to OS0 in TCSR of TMRX and bit P67DDR. OS3 to OS0 All 0 Not all 0 P67DDR 0 1 — Pin function P67 input pin P67 output pin TMOX output pin IRQ7 input pin, KIN7 input pin, CIN7 input pin This pin is used as the IRQ7 input pin when bit IRQ7E is set to 1 in IER. It can always be used as the KIN7 or CIN7 input pin. P66/FTOB/ IRQ6/ KIN6/CIN6 The pin function is switched as shown below according to the combination of bit OEB in TOCR of the FRT and bit P66DDR. OEB 0 1 P66DDR 0 1 — Pin function P66 input pin P66 output pin FTOB output pin IRQ6 input pin, KIN6 input pin, CIN6 input pin This pin is used as the IRQ6 input pin when bit IRQ6E is set to 1 in IER. It can always be used as the KIN6 or CIN6 input pin. P65DDR 0 1 P65/FTID/ KIN5/ CIN5 Pin function P65 input pin P65 output pin FTID input pin, KIN5 input pin, CIN5 input pin This pin can always be used as the FTID, KIN5, or CIN5 input pin. |
