PSC Registers—MBAR + 0x2000, 0x2200, 0x2400, 0x2600, 0x2800, 0x2C00
• Selectable pulse width: either 3/16 bit duration or 1.6 µs
IrDA MIR mode:
• Baud rate: 0.576 Mbps to 1.152 Mbps
IrDA FIR mode:

15.2 PSC Registers—MBAR + 0x2000, 0x2200, 0x2400, 0x2600, 0x2800, 0x2C00
The PSCs are located at an address as indicated below:
• PSC1 BASE = MBAR + 0x2000
• PSC2 BASE = MBAR + 0x2200
• PSC3 BASE = MBAR + 0x2400
• PSC4 BASE = MBAR + 0x2600
• PSC5 BASE = MBAR + 0x2800
• PSC6 BASE = MBAR + 0x2C00
Each PSC uses 42 registers. The register address is calculated as base address for the regarding PSC plus the offset value. Table 15-2 shows
the list with all implemented registers and the associated offset value.
