317 / 1075 page ![]() Section 9 8-Bit PWM Timers Rev. 3.00 Jan 18, 2006 page 289 of 1044 REJ09B0280-0300 9.2.7 Port 2 Data Direction Register (P2DDR) Bit Initial value Read/Write 7 P27DDR 0 W 6 P26DDR 0 W 5 P25DDR 0 W 4 P24DDR 0 W 3 P23DDR 0 W 0 P20DDR 0 W 2 P22DDR 0 W 1 P21DDR 0 W P2DDR is an 8-bit write-only register that specifies the input/output direction and PWM output for each pin of port 2 on a bit-by-bit basis. Port 2 pins are multiplexed with pins PW8 to PW15. The bit corresponding to a pin to be used for PWM output should be set to 1. For details on P2DDR, see section 8.3, Port 2. 9.2.8 Port 1 Data Register (P1DR) Bit Initial value Read/Write 7 P17DR 0 R/W 6 P16DR 0 R/W 5 P15DR 0 R/W 4 P14DR 0 R/W 3 P13DR 0 R/W 0 P10DR 0 R/W 2 P12DR 0 R/W 1 P11DR 0 R/W P1DR is an 8-bit readable/writable register used to fix PWM output at 1 (when OS = 0) or 0 (when OS = 1). For details on P1DR, see section 8.2, Port 1. 9.2.9 Port 2 Data Register (P2DR) Bit Initial value Read/Write 7 P27DR 0 R/W 6 P26DR 0 R/W 5 P25DR 0 R/W 4 P24DR 0 R/W 3 P23DR 0 R/W 0 P20DR 0 R/W 2 P22DR 0 R/W 1 P21DR 0 R/W P2DR is an 8-bit readable/writable register used to fix PWM output at 1 (when OS = 0) or 0 (when OS = 1). For details on P2DR, see section 8.3, Port 2. |
