The MCF52259RM is a mess regarding PSRR and PDSR registers.
Table 2-1 shows :
28 bits of PDSR
8 bits Pin wired-OR control.
No Slew rate control.
Figure 15-1 page 15-5 shows :
80 bits of PSRR (PSRR 0x10_0078, PSRRL 010_0080, PSRRH 0x10_0086)
80 bits of PDSR (PDSR 0x10_007C, PDSRL 010_0088, PDSRH 0x10_008E)
Paragraph 15.6.6 shows:
Reference to table 2-1. Alas most bits are not in there so one can only guess which bit controls which pin.
PSRR is gone. PSRRL has suddenly moved to 010_0078.
PDSR also gone. PDSRL *and* PDSRH have both suddenly moved to 0x10_007C.
I'd like to know how they really work.
Can anyone tell me please ?
