I/O PORTS (Cont’d)
7.5 REGISTER DESCRIPTION
DATA REGISTER (DR)
Port x Data Register
DRx with x = A or B.
Address DRA: 0C0h - Read/Write
Address DRB: 0C1h - Read/Write
Reset Value: 0000 0000 (00h)
Bit 7:0 = D[7:0] Data register bits.
Reading the DR register returns either the DR reg-
ister latch content (pin configured as output) or the
digital value applied to the I/O pin (pin configured
as input).
Caution: In input mode, modifying this register will
modify the I/O port configuration (see Table 8).
Do not use the Single bit instructions on I/O port
data registers. See (Section 7.2.5).
DATA DIRECTION REGISTER (DDR)
Port x Data Direction Register
DDRx with x = A or B.
Address DDRA: 0C4h - Read/Write
Address DDRB: 0C5h - Read/Write
Reset Value: 0000 0000 (00h)
Bit 7:0 = DD[7:0] Data direction register bits.
The DDR register gives the input/output direction
configuration of the pins. Each bit is set and
cleared by software.
0: Input mode
1: Output mode
OPTION REGISTER (OR)
Port x Option Register
ORx with x = A or B.
Address ORA: 0CCh - Read/Write
Address ORB: 0CDh - Read/Write
Reset Value: 0000 0000 (00h)
Bit 7:0 = O[7:0] Option register bits.
The OR register allows to distinguish in output
mode if the push-pull or open drain configuration is
selected.
Output mode:
0: Open drain output(with P-Buffer deactivated)
1: Push-pull Output
Input mode: See Table 8.
Each bit is set and cleared by software.
Caution: Modifying this register, will also modify
the I/O port configuration in input mode. (see Ta-
ble 8).
