• Description: Single-chip Solution, Compliant With Zigbee
• Manufacturer: California Eastern Laboratories

1.6 POWER MANAGEMENT
There are three Power-Down modes in the ZIC2410. Each mode can be set by PDMODE [1:0]
bits in PDCON (0x22F1) register and Power-Down mode can be started by setting PDSTART
bit to 1. Each mode has a different current consumption and different wake-up sources. Table
8 describes the three Power-Down modes.
EIP (EXTENDED INTERRUPT PRIORITY REGISTER, 0xF8)
If a bit is ‘0’, the corresponding interrupt has lower priority. If a bit is ‘1’, the corresponding interrupt
has higher priority.
EXIF (EXTENDED INTERRUPT FLAG REGISTER, 0x91)
This register stores the interrupt state corresponding to each bit. When the interrupt corresponding
to a bit is triggered, the flag is set to ‘1’.
