Reset
This register controls the pullups and pulldowns on MFR4200 pins identified in
function can be enabled/disabled by the PLPPER (see
Enable Register
1 – Pullup selected.
0 – Pulldown selected.
3.2.3.2.9
Address 0xA6
Reset
This register indicates the occurrence of internal low-voltage and/or power-on reset events caused by
power-on of MFR4200 device or supply voltage disturbances. The Low-voltage Status and Power-on
Status bits do not cause an interrupt over the INT_CC# pin; therefore, the host may read this register to
check the status.
The host clears any status bit in VREGSR by reading VREGSR. The CC sets a status bit in the VREGSR
again when it detects the condition for that bit.
