10.5.3 Port 2 Registers
The following registers are available on Port 2:
Note: The complete address map of Port 2 is described in Table 18-11 on Page 18-24
of this TC1796 System Units (Vol. 1 of 2) User’s Manual.
10.5.3.1 Port 2 Output Register
The basic P2_OUT register functionality is described on Page 10-13. Port lines P2.[1:0]
are not connected to port lines. Therefore, reading the P2_OUT bits P[1:0] returns the
value that was last written (0 after reset). These bits can be also set/cleared by the
corresponding P2_OMR bits.
10.5.3.2 Port 2 Output Modification Register
The basic P2_OMR register functionality is described on Page 10-14. However, port
lines P2.0 and P2.1 are not available. Therefore, the P2_OMR bits PS[1:0] and PR[1:0]
have no direct effect on port lines but only on register bits P2_OUT.P[1:0].
